TUOTE- VAI LIIKETOIMINTAOSAAMISTA? Pienten ja keskisuurten leipomoalan yritysten strategiset valinnat, liikkeenjohdon käytännöt ja menestyminen

Tutkimuksen aiheeksi valittiin yrityksen strategiset valinnat eli ne näkökulmat ja keinot, joiden avulla yritys toimii selviytyäkseen kilpailussa. Erityisesti tutkittiin osaamisen ja yleensäkin muun kuin fyysisiin tuotteisiin liittyvien yrityksen ominaisuuksien ja toimintatapojen liittymistä yrityksen menestymiseen. Lisäksi tutkittiin yrityksissä noudatettuja liikkeenjohdon käytäntöjä ja menetelmiä suhteessa strategisiin valintoihin. Tutkimuksen kohdetoimialaksi valittiin oli leipomoala, joka on suomalaisen elintarviketeollisuuden toimipaikkojen lukumäärällä mitattuna runsaslukuisin yksittäinen toimiala. Tutkimus toteutettiin lomakekyselynä, johon vastasi 90 suomalaista leipomoalan yritystä, jotka työllistivät enintään 49 henkilöä. Ryhmittelyanalyysin avulla kohdeyrityksistä muodostettiin neljä yritysryhmää erityisesti dynaamisuuden, innovatiivisuuden ja kustannustehokkuuden suhteen. Tutkimustulosten perusteella saatiin empiiristä evidenssiä sen suhteen, että innovatiivisuus ja dynaamisuus pienten ja keskisuurten leipomoalan yritysten strategiavalintana tuo yritykselle lisää valmiuksia yrityksen toiminnan kehittämiseen, mikäli yrityksen toimintaympäristö, erityisesti kilpailuympäristö muuttuu. Liikkeenjohdon, erityisesti laskentatoimen, käytännöt ja menetelmät todettiin tutkimuksen tulosten perusteella merkityksellisiksi tekijöiksi, joiden kautta strategiset valinnat vaikuttavat yrityksen menestymiseen. Näitä käytäntöjä ja menetelmiä voidaan näin ollen pitää yrityksen tärkeänä voimavarana ja osaamisen ilmentymänä.

Tuotekustannuslaskennan kehittäminen leipomoyrityksessä

Tutkimus käsittelee tuotekustannuslaskennan kehittämistä VAASAN Oy:ssä, joka on yksi johtavista leipomoyrityksistä Suomessa ja Baltiassa. Työn tavoitteena on kehittää tuotekustannuslaskentaa paremmin päätöksentekoa tukevaksi. Kehitystyössä otettiin huomioon laskentamallin joustavuuden säilyminen. Kehitystarpeet selvitettiin tuotekustannuslaskennan nykytilaanalyysillä sekä käyttäjäryhmien tietotarvekartoituksella. Kehityksen ohjaamiseen sovellettiin kustannustiedon laadukkuuden teorioita sekä riskienhallinnan työkalua. Lähtökohtana oli varsin hajautetusti toteutettu tuotekustannuslaskenta, minkä luotettavuuden ongelma tiedostettiin. Työn päätteeksi tuotekustannuslaskenta keskitetään. Keskittämisen tuoma tilaisuus halutaan käyttää mahdollisimman tehokkaasti hyödyksi kustannuslaskennan kehittämisessä. Ennen keskittämistä tulee tuotekustannuslaskenta johdonmukaistaa eri leipomoiden välillä. Tässä työssä kartoitettiin kehityskohteet sekä esitetään toimintamalli tai –ehdotus tärkeimpien kehityskohteiden ratkaisemiseksi. Tärkeimmät kehityskohteet löydettiin jäsentämällä ja priorisoimalla kehityskohteet. Tuotekustannuslaskentaa kehitettiin paremmin päätöksentekoa tukevaksi, johdonmukaisemmaksi, luotettavammaksi sekä sen käytettävyyttä kehitettiin.

Estrategias de internacionalización de la industria de panaderia en el mercado de la provincia de Shanxi China

China es el cuarto país más extenso del mundo así como el más densamente poblado. En la actualidad, se ha caracterizado por ser una economía con un papel importante en el comercio mundial. Es por este motivo, que en el año 2010 se convirtió en el país con más exportaciones en el mundo, ubicándose en las primeras economías después de los Estados Unidos. Por otro lado, China considera a Colombia como un país influyente en América Latina, lo que posibilita que en un futuro se puedan convertir en socios comerciales. Sin embargo, se debe resaltar que por su extensión, China es un país de diversas culturas por lo que el trabajo “Estrategias de internacionalización de la industria de panadería en Colombia hacia la provincia de Shanxi, China”, se centrara únicamente en la provincia de Shanxi. Dicha provincia es reconocida por su gran abundancia de recursos minerales, adicionalmente, juega un papel decisivo en la red eléctrica del Norte de China y planea convertirse en la base industrial del país por lo que promete un futuro próspero para su población convirtiéndose en un lugar potencial para centrar el trabajo. También, se debe resaltar el auge y crecimiento de la industria de panadería en Colombia ya que no solamente es perteneciente a la canasta familiar sino que es necesario y rentable para los empresarios. Además es una industria que genera productos de alta calidad y con valor agregado. Como toda industria colombiana esta también tienen ciertas falencias entre ellas se debe resaltar la falta de asociación; problemática en la cual se basara este trabajo ya que, como dice Anónimo 2011, “La importancia de su creación radica en que asociados, los panaderos podrían llegar fácilmente a encontrar soluciones a ese bajo consumo o incluso lograr alianzas para una mayor capacitación” y así facilitar la entrada a mercados internacionales. Para mostrar lo anterior, se analizaran 3 casos de empresas Colombianas, que muestran las diferentes etapas para entrar a un mercado internacional. La primera de ella Noel, con su trayectoria en el mercado Colombia, en este momento cuenta con presencia en varios países de Latinoamérica y Norteamérica. La segunda Pan Pa Ya que a través de su técnica de ultracongelación ha logrado conquistar países en Latinoamérica, Europa, Japón, Canadá entre otros. Finalmente se encuentra Ramo, empresa que aún no ha logrado entrar en mercados internacionales, pero se encuentra mejorando sus procesos para internacionalizarse y para llegar a aquellos colombianos que viven en el exterior. Como complemento se busca resaltar la importancia de la asociación y la creación de clústeres de las empresas colombianas para la generación de productos de alta calidad que satisfagan las condiciones requeridas para entrar en nuevos mercados, teniendo en cuenta las pautas necesarias para generar ventajas competitivas y estrategias de internacionalización

Identifying innovation strategies:insights from the greek food industry

This paper emphasizes on the concept of innovation which is more and more nowadays recognized as of significant importance for all companies across different business sectors. The paper initially provides a review of the innovation literature in terms of types, classifications, and sources of innovation that have been proposed over time. Then, innovation in the context of the food industry is examined and it is attempted to identify innovation strategies followed by Greek food companies based on a value driven approach of innovation. The paper finally, provides insights from eight Greek food companies, which were selected from four subsectors: fruit and vegetables, dairy products, meat products (cured meats), and bakery products. The criterion used for the selection was market success and outstanding performance (e.g. market share, achieved results). Evidence indicates that companies tend to innovate along the dimension of offerings, which is more related to the traditional view of product and process innovation.

Combined photocatalytic and fungal processes for the treatment of nitrocellulose industry wastewater

The objective of this work was to characterize the delignification effluent originating from the delignification industry and evaluate the combination of the fungus and photocatalytic process (TiO(2)/UV system) for the treatment of this effluent. The delignification effluent has proven harmful to the environment because it presents high color (3516 CU), total phenol (876 mg/L and TOC (1599 mg/L) and is also highly toxic even in a low concentration. The results of photocatalysis were 11%, 25% and 13% higher for reductions in color, total phenol and TOC, respectively. The combined treatments presented benefits when compared to the non-combined treatments. Fungus and photocatalysis in combination proved to be the best treatment, reducing the color, total phenol, toxicity (inhibition of Escherichia coli growth) and TOC by 94.2%, 92.6%, 4.9% and 62%, respectively.

AnSBBR Applied to a Personal Care Industry Wastewater Treatment: Effects of Fill Time, Volume Treated Per Cycle, and Organic Load

A study was performed regarding the effect of the relation between fill time, volume treated per cycle, and influent concentration at different applied organic loadings on the stability and efficiency of an anaerobic sequencing batch reactor containing immobilized biomass on polyurethane foam with recirculation of the liquid phase (AnSBBR) applied to the treatment of wastewater from a personal care industry. Total cycle length of the reactor was 8 h (480 min). Fill times were 10 min in the batch operation, 4 h in the fed-batch operation, and a 10-min batch followed by a 4-h fed batch in the mixed operation. Settling time was not necessary since the biomass was immobilized and decant time was 10 min. Volume of liquid medium in the reactor was 2.5 L, whereas volume treated per cycle ranged from 0.88 to 2.5 L in accordance with fill time. Influent concentration varied from 300 to 1,425 mg COD/L, resulting in an applied volumetric organic load of 0.9 and 1.5 g COD/L.d. Recirculation flow rate was 20 L/h, and the reactor was maintained at 30 A degrees C. Values of organic matter removal efficiency of filtered effluent samples were below 71% in the batch operations and above 74% in the operations of fed batch followed by batch. Feeding wastewater during part of the operational cycle was beneficial to the system, as it resulted in indirect control over the conversion of substrate into intermediates that would negatively interfere with the biochemical reactions regarding the degradation of organic matter. As a result, the average substrate consumption increased, leading to higher organic removal efficiencies in the fed-batch operations.

Anaerobic sequencing batch biofilm reactor applied to automobile industry wastewater treatment: Volumetric loading rate and feed strategy effects

This paper presents a technological viability study of wastewater treatment in an automobile industry by an anaerobic sequencing batch biofilm reactor containing immobilized biomass (AnSBBR) with a draft tube. The reactor was operated in 8-h cycles, with agitation of 400 rpm, at 30 degrees C and treating 2.0 L wastewater per cycle. Initially the efficiency and stability of the reactor were studied when supplied with nutrients and alkalinity. Removal efficiency of 88% was obtained at volumetric loading rate (VLR) of 3.09 mg COD/L day. When VLR was increased to 6.19 mg COD/L day the system presented stable operation with reduction in efficiency of 71%. In a second stage the AnSBBR was operated treating wastewater in natura, i.e., without nutrients supplementation, only with alkalinity, thereby changing feed strategy. The first strategy consisted in feeding 2.0 L batch wise (10 min), the second in feeding 1.0 L of influent batch wise (10 min) and an additional 1.0 L fed-batch wise (4 h), both dewatering 2.0 L of the effluent in 10 min. The third one maintained 1.0 L of treated effluent in the reactor, without discharging, and 1.0 L of influent was fed fed-batch wise (4 h) with dewatering 1.0 L of the effluent in 10 min. For all implemented strategies (VLR of 1.40, 2.57 and 2.61 mg COD/L day) the system presented stability and removal efficiency of approximately 80%. These results show that the AnSBBR presents operational flexibility, as the influent can be fed according to industry availability. In industrial processes this is a considerable advantage, as the influent may be prone to variations. Moreover, for all the investigated conditions the kinetic parameters were obtained from fitting a first-order model to the profiles of organic matter, total volatile acids and methane concentrations. Analysis of the kinetic parameters showed that the best strategy is feeding 1.0 L of influent batchwise (10 min) and 1.0 L fed-batch wise (4 h) in 8-h cycle. (c) 2007 Elsevier B.V.

Coloured Petri nets and graphical simulation for the validation of a robotic cell in aircraft industry

This paper proposes a mixed validation approach based on coloured Petri nets and 3D graphic simulation for the design of supervisory systems in manufacturing cells with multiple robots. The coloured Petri net is used to model the cell behaviour at a high level of abstraction. It models the activities of each cell component and its coordination by a supervisory system. The graphical simulation is used to analyse and validate the cell behaviour in a 3D environment, allowing the detection of collisions and the calculation of process times. The motivation for this work comes from the aeronautic industry. The automation of a fuselage assembly process requires the integration of robots with other cell components such as metrological or vision systems. In this cell, the robot trajectories are defined by the supervisory system and results from the coordination of the cell components. The paper presents the application of the approach for an aircraft assembly cell under integration in Brazil. This case study shows the feasibility of the approach and supports the discussion of its main advantages and limits. (C) 2011 Elsevier Ltd. All rights reserved.

Toxicity-directed approach of polyester manufacturing industry wastewater provides useful information for conducting treatability studies

A broader characterization of industrial wastewaters, especially in respect to hazardous compounds and their potential toxicity, is often necessary in order to determine the best practical treatment (or pretreatment) technology available to reduce the discharge of harmful pollutants to the environment or publicly owned treatment works. Using a toxicity-directed approach, this paper sets the base for a rational treatability study of polyester resin manufacturing. Relevant physical and chemical characteristics were determined. Respirometry was used for toxicity reduction evaluation after physical and chemical effluent fractionation. Of all the procedures investigated, only air stripping was significantly effective in reducing wastewater toxicity. Air stripping in pH 7 reduced toxicity in 18.2%, while in pH 11 a toxicity reduction of 62.5% was observed. Results indicated that toxicants responsible for the most significant fraction of the effluent`s instantaneous toxic effect to unadapted activated sludge were organic compounds poorly or not volatilized in acid conditions. These results led to useful directions for conducting treatability studies which will be grounded on actual effluent properties rather than empirical or based on the rare specific data on this kind of industrial wastewater.

New reconciliation model for gold industry

Reconciliation can be divided into stages, each stage representing the performance of a mining operation, such as: long-term estimation, short-term estimation, planning, mining and mineral processing. The gold industry includes another stage which is the budget, when the company informs the financial market of its annual production forecast. The division of reconciliation into stages increases the reliability of the annual budget informed by the mining companies, while also detecting and correcting the critical steps responsible for the overall estimation error by the optimization of sampling protocols and equipment. This paper develops and validates a new reconciliation model for the gold industry, which is based on correct sampling practices and the subdivision of reconciliation into stages, aiming for better grade estimates and more efficient control of the mining industry`s processes, from resource estimation to final production.

OPTIMIZATION OF THE TREATMENT PROCESS FOR RESIDUAL WATER FROM A BEER INDUSTRY

The optimization of the treatment process for residual waters from a brewery operating under the modality of an anaerobic reactor and activated sludge combination was studied in two phases. In the first stage, lasting for six months, the characteristics and parameters of the plant operation were analyzed, wherein a diversion rate of more than 50% to aerobic treatment, the use of two aeration tanks and a high sludge production prevailed. The second stage comprised four months during which the system worked under the proposed operational model, with the aim of improving the treatment: reduction of the diversion rate to 30% and use of only one aeration tank At each stage, TSS, VSS and COD were measured at the entrance and exit of the anaerobic reactor mid the aeration tanks. The results were compared with the corresponding design specifications and the needed conditions were applied to reduce the diversion rate towards the aerobic process through monitoring the volume and concentration of the affluent, while applying the strategic changes in reactor parameters needed to increase its efficiency. A diversion reduction from 53 to 34% was achieved, reducing the sludge discharge generated in the aerobic system from 3670mg TSS/l. with two aeration tanks down to 2947mf TSS/l using one tank keeping the same relation VSS:TSS (0.55) and an efficiency of total removal of 98% in terms of COD.

Wine industry residues extracts as natural antioxidants in raw and cooked chicken meat during frozen storage

The effect of Isabel (IGE) and Niagara (NGE) grape seed and peel extracts on lipid oxidation, instrumental colour, pH and sensory properties of raw and cooked processed chicken meat stored at -18 degrees C for nine months was evaluated. The pH of raw and cooked samples was not affected by the addition of grape extracts. IGE and NGE were effective in inhibiting the lipid oxidation of raw and cooked chicken meat, with results comparable to synthetic antioxidants. The extracts caused alterations in colour, as evidenced by the instrumental (darkening and lower intensity of red and yellow colour) and sensory results of cooked samples. In the sensory evaluation of odour and flavour, IGE produced satisfactory results, which did not differ from synthetic antioxidants. These findings suggest that the ICE and NGE are effective in retarding lipid oxidation of raw and cooked chicken meat during frozen storage. (c) 2011 Elsevier Ltd. All rights reserved.
