Rad predstavlja prikaz metodologije koja koristi Lean pristup u pokretanju preduzetničkih poduhvata. Ova metodologija je, u stranoj literaturi, poznata pod akronimom Lean Startup i nastala je po analogiji sa Lean pristupom u procesu proizvodnje (engl. Lean Manufacturing). Usled oskudnosti raspoloživih poslovnih resursa i eliminisanja suvišnih i nepotrebnih aktivnosti i kreiranja proizvoda ili usluge isključivo prema potrebama kupaca i krajnjih korisnika, Lean Startup pristup ima za cilj da ponudi adekvatnu metodologiju u razvoju novih preduzetničkih poduhvata. Nezaobilazni element u metodologiji "Lean Startup" je izgradnja Canvas poslovnog modela, čija je svrha utvrđivanje vrednosti ideje o budućem preduzetničkom poduhvatu: proizvodima/uslugama, kao i o ključnim resursima, aktivnostima, stejkholderima, strukturi troškova i tokovima novca. U radu je predstavljen i pristup unapređenju Canvas modela prema autoru Maurya (2012), poznat pod nazivom "Lean Canvas poslovni model".

Rad predstavlja prikaz problema raspoređivanja u procesu planiranja proizvodnje koji je karakterističan za proizvodna mala i srednja proizvodna preduzeća (MSP). Job Shop (JS) je problem raspoređivanja operacija obrade nekoliko proizvoda na nekoliko mašina, pri čemu proizvodi mogu imati različit redosled obrade. S obzirom da proizvodna MSP imaju ograničen količine i vrste proizvodnih resursa, što može dodatno da oteža proces planiranja proizvodnje, klasičan problem JS mora da se dodatno proširi. U radu je predstavljeno proširenje klasičnog JS problema, posmatranjem više od jedne vrste raspoloživih resursa (mašina i radnika) koji mogu biti fleksibilni u pogledu realizacije operacija obrade, koji je poznat pod nazivom dvoresursno ograničen Flexible Job Shop problem. Predstavljen je matematički model i prikazana jedna od mogućnosti za rešavanje ovog problema-preko procesa iterativnog generisanja lokalnih dopustivih rešenja. Ključne reči: Planiranje proizvodnje, MSP, Job Shop, dvoresursno ograničeni Flexible Job Shop problem.

This paper proposes a way to help in solving the high levels of unemployment amongst the young (in Serbia) – by designing and realising stakeholders’ programmes which would allow inclusion of the young in the entrepreneurial world (through either self-employment or employment of others). The idea is to identify and recommend to stakeholders the competencies and motives that drive the nowadays young entrepreneurs – as models for enabling and motivating unemployed youth to engage into the entrepreneurial world. On the basis of facts obtained by research – which pinpoint the competencies - both practical and theoretical, on the basis of the motives of the young entrepreneurs in Serbia, as well as on the basis of their beliefs/attitudes about the same aspects of starting and undertaking entrepreneurial projects, some recommendations for stakeholders have been generated for designing a programme to encourage those young people to join the ranks of entrepreneurs. What remains is for the relevant authorities - in the legal and even family settings, i.e., all those who can recognise some self-interest, is to get started and dedicate themselves to the young and their entry into the world of entrepreneurship. The contribution of this paper is in the suggestions for the different types of stakeholders which would help them design programmes to bring the young generations into the entrepreneurial sphere. We also consider even the very fact of pointing out the different roles of the varied social subjects/stakeholders to be useful in bringing the younger generations into the world of entrepreneurship, as a form of care for the young generations.

Entrepreneurship in the public sector is a form of entrepreneurship which is currently being implemented in public companies, state and/or local government and public institutions. It is often recognized as part of operations management because it relies on: the operations that change conditions of enterprises, ideas, innovation, resources, actions, planning, and other areas of operations management. This paper is part of the survey on entrepreneurship in the public sector of Serbia, which was carried out by the FOS Center for Entrepreneurship and SMEs in 2014 by interviewing 65 employees in the public sector. The aim of the survey was to explore whether the Serbian public sector was ready for entrepreneurial concept - through public sector employees’ awareness of the concept of entrepreneurship, as well as through the application of entrepreneurial practice in public enterprises and organizations. The results showed a low level of employees’ awareness of the entrepreneurship concept, as well as a low level of implementation of this concept in the public sector of Serbia. Based on the results presented in this paper, it can be concluded that it is necessary to stimulate the development of entrepreneurship concept in the public sector, primarily by further informing management and employees of the public sector about the potentials of entrepreneurship, and also educating them to use the possibilities and opportunities for the application of this concept.

Stock cover is presented by a key performance indicator calculating the number of days of forecasted consumption which the current stock level can face. The identified problem in production companies, when calculating the “Stock Cover” indicator companies opt for one of three ways, among which there are large deviations in planning frequency and launching the orders for procurement or/and production, as well as a wide aberration in the volume of customer orders; which directly affects costs and competitiveness of enterprises. The idea of the authors of this study was to make “Stock cover” indicator and “Balanced Stock Cover” to be more adequate, and at the same time more efficient and effective in the operational management of a company

The paper focuses on the research of support provided to agricultural farms (AF) in Serbia, which are, in this paper, considered as SMEs. The basic idea of this paper is to analyze the support that is necessary to be provided to the existing AF in modern Serbia, with the aim of improving the level of quality in managing their business. The intention of the authors is to: 1. Explore Afs’ expectations from support; 2. Determine the level of these expectations achievement; and 3. Determine the critical areas where support is not at an adequate level, all with the aim of successful (effective and efficient) planning of support to AFs. The results of this study are intended for AFs, the state and its institutions that provide support to AFs and other stakeholders.
