Aine- ja tarvikevarastojen varasto-ohjauksen ja raportoinnin

Työn tavoitteena oli selvittää OMG Kokkola Chemicals Oy:n aine- ja tarvike varastojen materiaalin ohjauksen sekä raportoinnin nykytila, analysoida saatuja tuloksia ja pohtia keinoja hankintatoimintaan ja raportointiin liittyvien menetelmien parantamiseksi. Pääpaino materiaalin ohjauksen kehittämistoimenpiteiden osalta oli varastoihin sitoutuneiden pääomien vapauttaminen ja palvelutason parantaminen. Raportoinnin osalta työssä keskityttiin varaston valvonnan kehittämiseen. Varastojärjestelmä Matekista saatuja ABC-analyysejä käytettiin apuna painopisteiden määrittämisessä nimikkeistön nykytilan tarkastelussa. Vuosi käytöltään merkittävimpiä nimikkeitä tarkasteltiin yksityiskohtaisesti. Matekin vakituisen käytön ulkopuolisia raportointiominaisuuksia tarkasteltiin tekemällä koeajoja sekä lisäksi tutkittiin Cognos Impromptu-ohjelman tuomia lisä mahdollisuuksia raportointiin. Työssä esitettiin keinot tilauspistejärjestelmän parametrien määrittämiseksi. Valituille nimikkeille laskettiin varmuusvarastotasot, hälytysrajat ja täydennys eräkoot sekä esitettiin laskelmat saavutettavista pääomakustannussäästöistä vanhan järjestelmän parametreihin verrattuna. Tuotannon ja oston välisen yhteistyön avulla saavutettavia säästöjä varastokustannustenosalta tarkasteltiin materiaali tarvelaskennan avulla. Ostostrategiantarkastelun ja kehittämisen työkaluna käytettiin ostosalkkuanalyysiä. Säännöllisten raporttien lisäksi esitettiin käyttöön otettaviksi uusia raportteja, joiden avulla voidaan seurata nimikkeistön hinnanmuutoksia ja epäkurantin osuutta varastossa. Raporttien laatimisen lähtökohdat Cognos Impromptulla käytiin läpi ja esitettiin menetelmän avulla saavutettavat hyödyt ja esiintyneet ongelmat.

Tilauspisteen ja tilauseräkoon määrittäminen osana ostoprosessin kehittämistä tukkukaupassa

Varastojen hallinta sisältää yksinkertaisimmillaan varastotasojen, tilauspisteiden ja tilauseräkokojen määrittämiseen liittyviä päätöksiä ja toimenpiteitä. Perinteisesti näitä päätöksiä on tarkasteltu ainoastaan yhden ohjauspisteen sisäisestä näkökulmasta. Ostoprosessin ja siihen liittyvien toimittajasuhteiden kehittämisen merkitystä varastojen hallinnassa ei ole sen sijaan täysin ymmärretty. Tässä työssä tarkastellaan sekä perinteisiä varastonohjausjärjestelmiä että ostoprosessin kehittämistä teoreettisen viitekehyksen ja empiirisen case-tutkimuksen kautta. Tutkimuksen päätarkoitus on esittää varastonimikkeiden tilausajankohdan ja –eräkoon määrittämiseen liittyviä menetelmiä. Tutkimuksen teoriaosassa muodostetaan viitekehys tuotteiden luokitteluun perustuville varastojen hallinnan menettelytavoille. Varastojen hallinnan päätöksiin vaikuttavia tekijöitä ovat mm. ostoprosessin vaiheiden operatiivinen kehittäminen, toimittajayhteistyön parantaminen toimitusketjun hallinnan ja partnership-suhteiden kautta sekä nimikkeiden kysynnän, toimitusaikojen, varastojen hallinnan kustannusten ja mittarien määrittäminen. Lisäksi kuvataan tukkukauppaan liittyviä erityispiirteitä em. seikkojen osalta. Empiirisessä osassa tarkastellaan ensin terästuotteiden tukkukaupan Oy Kontino Ab:n ostotoiminnan ja varastojen hallinnan nykytilaa. Haastatteluaineiston perusteella esitetään optimaalisia varastotäydennysmenetelmiä luokitelluille nimikkeille. Tutkimuksen mukaan varaston palvelukyvyn mittaaminen on välttämätöntä optimaalisen tilauspisteen ja –eräkoon määrittämisessä. Tukkukaupan varastojen hallintaan soveltuu parhaiten kiinteän tilausvälin järjestelmä, jossa tilaushetki on kiinteä ja eräkoko sekä tilauspiste vaihtelevat. Tutkimuksesta voidaan päätellä, että myös tukkukaupan on pyrittävä varastotasojen alentamiseen parantaakseen varastoinnin tehokkuutta ja palvelukykyä. Parannukset voidaan toteuttaa vain ymmärtämällä varastojen hallinnan ja ostoprosessin välinen läheinen yhteys ja kehittämällä strategista toimittajayhteistyötä.

Gestão de estoques: uma proposta de reposição contínua para material médico hospitalar e medicamentos em um hospital universitário federal do estado do Rio Grande do Norte

The inventory management in hospitals is of paramount importance, since the supply materials and drugs interruption can cause irreparable damage to human lives while excess inventories involves immobilization of capital. Hospitals should use techniques of inventory management to perform replenishment in shorter and shorter intervals, in order to reduce inventories and fixed assets and meet citizens requirements properly. The inventory management can be an even bigger problem for public hospitals, which have restrictions on the use of resources and decisionmaking structure more bureaucratized. Currently the University Hospital Onofre Lopes (HUOL) uses a periodic replacement policy for hospital medical supplies and medicines, which involves one moment surplus stock replenishment, the next out of stock items. This study aims to propose a system for continuous replenishment through order point for inventory of medical supplies and medicines to the hospital HUOL. Therefore, a literature review of Federal University Hospitals Management, Logistics, Inventory Management and Replenishment System in Hospitals was performed, emphasizing the demand forecast, classification or ABC curve and order point system. And also, policies of inventory management and the current proposal were described, dealing with profile of the mentioned institution, the current policy of inventory management and simulation for continuous replenishment order point. For the simulation, the sample consisted of 102 and 44 items of medical and hospital drugs, respectively, selected using the ABC classification of inventory, prioritizing items of Class A, which contains the most relevant items in added value, representing 80 % of the financial value in 2012 fiscal year. Considering that it is a public organization, subject to the laws, we performed two simulations: the first, following the signs for inventory management of Instruction No. 205 (IN 205 ), from Secretary of Public Administration of the Presidency ( SEDAP / PR ), and the second, based on the literature specializing in inventory management hospital. The results of two simulations were compared to the current policy of replenishment system. Among these results are: an indication that the system for continuous replenishment reorder point based on IN 205 provides lower levels of safety stock and maximum stock, enables a 17% reduction in the amount spent for the full replenishment of inventories, in other words, decreasing capital assets, as well as reduction in stock quantity, also the simulation made from the literature has indicated parameters that prevent the application of this technique to all items of the sample. Hence, a change in inventory management of HUOL, with the application of the continuous replenishment according to IN 205, provides a significant reduction in acquisition costs of medical and hospital medicine

Características cineantropométricas en jugadores de baloncesto adolescentes

Introducción: El baloncesto presenta una gran heterogeneidad antropométrica entre jugadores en relación a la posición de juego. El base suele ser el más bajo del equipo pero también el más rápido. El escolta suele ser similar al base, más bajo, rápido y ágil que el resto. El alero es de una altura intermedia entre los jugadores interiores y exteriores, combina la altura con la velocidad, y el pívot tiene un rol más físico, es el más alto y con mayor masa muscular. El objetivo del estudio es describir el perfil cineantropométrico del equipo cadete masculino del Valencia Basket Club. Material y Métodos: Se han evaluado 20 jugadores de baloncesto cadete masculino (15,35±0,59años). Un antropometrista nivel I tomó las medidas según la metodología de la Society for the Advancement of Kinanthropometry (ISAK). Se calculó la composición corporal según el consenso de cineantropometría del Grupo Español de Cineantropometría (GREC), el somatotipo según Heath-Carter, e índices adiposo-musculares. Resultados: Se observaron diferencias en los valores de peso, talla, pliegues cutáneos y composición corporal, de las variables estudiadas de la muestra total y por posición de juego, siendo los valores menores los de la posición base y mayores en los pívots. Se estableció una tendencia creciente de estos parámetros en el siguiente orden: base, escolta, alero y pívot. Conclusiones: El somatotipo global del jugador de baloncesto cadete del Valencia Basket Club es ectomorfo balanceado. Conocer el perfil cineantropométrico puede beneficiar la elaboración de planes de entrenamiento y nutrición, así como reflejar la evolución y dirigirla hacia las características ligadas al rendimiento óptimo.

Central Stores Inventory: Employing the IBM 1410 Magnetic Tape Computer System

The Property and Equipment Department has a central supply of automotive parts, tools, and maintenance supplies. This central supply is used to supply the repair shop and also to supply parts to the various field garages and all departments of the Commission. The old procedure involved keeping track manually of all of the parts, which involved some 22,000 items. All records, billings, arid re-order points were kept manually. Mani times the re-order points were located by reaching into a bin and finding nothing there. Desiring to improve this situation, an inventory control system was established for use on the computer. A complete record of the supplies that are stored in the central warehouse was prepared and this information was used to make a catalog. Each time an item is issued or received, it is processed through the inventory program. When the re-order point is reached, a notice is given to reorder. The procedure for taking inventory has been improved. A voucher invoice is now prepared by the computer for all issues to departments. These are some of the many benefits that have been de rived from this system.

Offshore wind turbine simulation: multibody drive train. Bacl-to-back NPC (Neutral Point Clamped) converters: Fractional-order control

This paper is on offshore wind energy conversion systems installed on the deep water and equipped with back-to-back neutral point clamped full-power converter, permanent magnet synchronous generator with an AC link. The model for the drive train is a five-mass model which incorporates the dynamic of the structure and the tower in order to emulate the effect of the moving surface. A three-level converter and a four-level converter are the two options with a fractional-order control strategy considered to equip the conversion system. Simulation studies are carried out to assess the quality of the energy injected into the electric grid. Finally, conclusions are presented. (C) 2014 Elsevier Ltd. All rights reserved.

Fixed point transformations in the adaptive control of fractional-order MIMO systems

Though the formal mathematical idea of introducing noninteger order derivatives can be traced from the 17th century in a letter by L’Hospital in which he asked Leibniz what the meaning of D n y if n = 1/2 would be in 1695 [1], it was better outlined only in the 19th century [2, 3, 4]. Due to the lack of clear physical interpretation their first applications in physics appeared only later, in the 20th century, in connection with visco-elastic phenomena [5, 6]. The topic later obtained quite general attention [7, 8, 9], and also found new applications in material science [10], analysis of earth-quake signals [11], control of robots [12], and in the description of diffusion [13], etc.

Saddle Point and Second Order Optimality in Nondifferentiable Nonlinear Abstract Multiobjective Optimization

This article deals with a vector optimization problem with cone constraints in a Banach space setting. By making use of a real-valued Lagrangian and the concept of generalized subconvex-like functions, weakly efficient solutions are characterized through saddle point type conditions. The results, jointly with the notion of generalized Hessian (introduced in [Cominetti, R., Correa, R.: A generalized second-order derivative in nonsmooth optimization. SIAM J. Control Optim. 28, 789–809 (1990)]), are applied to achieve second order necessary and sufficient optimality conditions (without requiring twice differentiability for the objective and constraining functions) for the particular case when the functionals involved are defined on a general Banach space into finite dimensional ones.

Rounding of a first-order quantum phase transition to a strong-coupling critical point

We investigate the effects of quenched disorder on first-order quantum phase transitions on the example of the N-color quantum Ashkin-Teller model. By means of a strong-disorder renormalization group, we demonstrate that quenched disorder rounds the first-order quantum phase transition to a continuous one for both weak and strong coupling between the colors. In the strong-coupling case, we find a distinct type of infinite-randomness critical point characterized by additional internal degrees of freedom. We investigate its critical properties in detail and find stronger thermodynamic singularities than in the random transverse field Ising chain. We also discuss the implications for higher spatial dimensions as well as unusual aspects of our renormalization-group scheme. DOI: 10.1103/PhysRevB.86.214204
