Munkaszervezés a lean termelésben – mit magyaráznak a termelésmenedzsment koncepciók = Work organization in lean production – what production concepts explain

A tanulmány a lean termelés munkaszervezését három termelésmenedzsment koncepció segítségével vizsgálja. Az egyes koncepciók a szervezet eltérő metszeteit érintik: (1) a termék-folyamat mátrix (Hayes és Wheelwright, 1979) a termék és a folyamat jellemzőit helyezi középpontba. A lean hatására a szervezet a mátrixban a nagyobb választék és a folyamat alapú működés (nagyobb függőség) irányába mozdul el. Az elmozdulást üzemi szinten a magas elkötelezettségű munkavégzési rendszer gyakorlatainak bevezetése kíséri, mivel azok támogatják a rugalmas működést, a gyors kommunikációt és problémamegoldást. Az elmozdulás „minősége” és így a munkaszervezési gyakorlatok használata (mélyég, száma, munkavállalók bevonása) nagyban függ a termelési stratégiától és a lean érettségtől. (2) A termelési stratégia szakaszai (Wheelwright és Hayes, 1985) a termelés üzleti stratégiában játszott szerepét elemzik. A lean termelés összeegyeztethető a termelési stratégia harmadik szakaszának „command és control” szemléletmódjával. Az ilyen lean termelők költégfókuszúak, a hagyományos munkaerőképben gondolkodnak és körükben kevésbé jellemző az új emberi erőforrás gyakorlatok használata. A lean termelés adaptálása ösztönözheti a vállalatokat a termelési stratégia negyedik szintje felé. A negyedik szint a bevonásra, problémamegoldásra és tanulásra épít, amely megfelel a lean „emberek tisztelete” pillérének. (3) A lean érettségi modell (Hines és társai, 2004) a lean szervezeten belüli elmélyülését és terjedését mutatja be. A lean utazás során a vállalatok az eszköz alapú megközelítéstől a komplex értékrendszerben gondolkodó lean szervezet felé haladnak. A technikai tudásanyag egyre szélesebb körűvé válik, ami rávilágít a tudásátadás (személyek közöttire, de akár struktúrákba, folyamatokba építése is) képességének jelentőségére. Az emberi erőforrás gyakorlatok folyamatosan jelennek meg. De csak a legfejlettebb szakasz, a lean tanuló szervezet megjelenése teszi valóban szükségessé a munkavállalói kép újragondolását is. = This paper examines work organization in lean production with the help of three production concepts. These concepts embrace different dimensions of the organization: (1) the product-process matrix (Hayes and Wheelwright, 1979) is about product and process characteristics. Due to the lean the organization shifts within the matrix – towards higher variability and flow (higher level of interdependencies). On the shop floor the shift is accompanied by the introduction of high commitment work system’s practices, since those support flexible operations, fast communication and problem-solving. The „quality” of the shift and hence the application of these work practices (number of practices, their embeddeness, employee involvement) highly depends on manufacturing strategy and lean maturity. (2) The concept of stages of manufacturing strategy (Wheelwright and Hayes, 1985) analyzes the role of the manufacturing function in the business strategy. Lean production is compatible with the „command and control” approach of the third stage of manufacturing strategy. These lean producers are cost-driven, they have the traditional approach of employees and apply new work organization practices to a less extent. However, the implementation of lean production may drive these companies to the fourth stage. The fourth stage of manufacturing strategy is based on employee involvement, problem-solving and learning. This stage is in full accordance with the „respect for people” pillar of lean production. (3) Lean maturity (Hines et al., 2004) shows the path how lean management deepens and expands within an organization. During the lean journey, companies progress from the tool-based approach to the complex lean value system. The technical knowledge of lean becomes more and more comprehensive and it points out the crucial importance of knowledge conversion capabilities (intrapersonal or even how to build knowledge into structures, processes). Work organization practices constantly appear with the progress, but the review of the traditional approach of employees is only essential at the most advanced stage, when an organization becomes lean learning organization.

Polluting production – environmentally sound alternatives; A general model of production externalities

With the determination of principal parameters of producing and pollution abatement technologies, this paper quantifies abatement and external costs at the social optimum and analyses the dynamic relationship between technological development and the above-mentioned costs. With the partial analysis of parameters, the paper presents the impacts on the level of pollution and external costs of extensive and intensive environmental protection, market demand change and product fees, and not environmental protection oriented technological development. Parametrical cost calculation makes the drawing up of two useful rules of thumb possible in connection with the rate of government in-terventions. Also, the paradox of technological development aiming at intensive environmental protection will become apparent.

Decision support system for production control: Multiple criteria decision making in practice

This paper presents a development of decision support systems for solving scheduling problems. It consists of two parts — the first describing the production processes which can be handled by the system and the second describing how the system works.

Climate or rural development policy?

Being heavily energy dependent, it is not much of a surprise that Europe pays special attention to reducing the use of fossil fuels. Each one of the ten new member states is characterized by relatively low per capita energy consumption and relatively low energy efficiency, and the share of renewables in their energy mix tends to be low, too. The paper examines the problem when policy measures create a decrease in environmental capital instead of an increase. In this case it hardly seems justified to talk about environmental protection. The authors describe a case of a Hungarian rapeseed oil mill which would not be of too much interest on its own but given that almost all similar plants went bankrupt, there are some important lessons to learn from its survival. The enterprise the authors examined aimed at establishing a micro-regional network. They completed a brown-field development to establish a small plant on the premises of a former large agricultural cooperative. By partnering with the former employees and suppliers of the sometime cooperative, they enjoyed some benefits which all the other green-field businesses focusing on fuel production could not. The project improved food security, energy security and population retention as well.

Lean termelés és üzleti teljesítmény – nemzetközi empirikus eredmények (Lean production and business performance – international empirical results)

A lean termelés javít a vállalatok operatív teljesítményén. Korábbi kutatásokkal összhangban ezt nemzetközi kérdőíves felmérésből származó eredmények is alátámasztják. Nem mutatható ki azonban egyértelmű kapcsolat a lean termelés és az üzleti teljesítmény között. A szerzők kutatásukban – kifejezetten a több lean eszközt elmélyülten használó és jó operatív eredményekkel rendelkező ún. haladó lean termelők üzleti eredményeire fókuszálva – azonosították az üzleti teljesítményt befolyásoló tényezőket. Bár számos tényező kívül esik a termelésmenedzsment hatáskörén (pl. piaci dinamika, új piacra lépők száma, személyre szabás), de a termék/szolgáltatás arányának befolyásolásán, a beszállítók és a kapacitástartalékok menedzsmentjén keresztül a termelésnek is van lehetősége az üzleti teljesítmény javítására. Végül, bár közvetlen kapcsolat nem mutatható ki a lean termelés és az üzleti teljesítmény között, de a szerzők várakozásai szerint a folyamatosan javuló operatív teljesítmény kiegyensúlyozott és stabil üzleti teljesítmény alapja lehet. A haladó lean vállalatok pedig nagyobb eséllyel kerülhetnek (maradhatnak?) a jó üzleti teljesítménnyel büszkélkedő vállalatok körébe(n). ____________ The lean production has improved the operational performance of companies. However a clear link between lean production and business performance can not be detected. In their research the authors have identified the factors affecting business performance focusing on business results of the advanced lean producers. Although a direct connection is not detected between lean production and business performance, but according to the author expects the continuously improving operational performance shall be a base for the balanced and stable business performance.

Open innovation in the performing arts. Examples from contemporary dance and theatre production

Scholarship on open innovation examines the different shades of opening up the innovation process of firms, where the most important feature is sourcing in knowledge. In this paper I examine the implications of adapting open innovation frames to a field where it was not investigated before: performing arts (contemporary dance and theatre). I draw on case studies and demonstrate that open innovation strategies are viable for artistic production. Independent companies purposefully mining out external knowledge in production, and commercializing on the spillovers of their body of knowledge, put themselves on the shelf of firms adopting and adapting to open innovation.

Land Policy and Farm Structure: Challenges and Opportunities for Agriculture in the Western Balkan

Although Western Balkan countries are quite different, they can all be characterised by their one shared goal, to achieve the quickest possible accession to the European Union. Even though agriculture plays an important key role within all Western Balkan states, it’s share is the highest in Albania and only Serbia has a trade surplus. Land is a key production factor but all the analysed countries can be characterized by fragmented land structure and low average farm sizes. Mostly based on land ownership issues, a land reform index can be calculated. The major contribution of this paper to the literature is the reevaluated land reform index for the Western Balkans.
