“…Tiekėjų atranka visuotinai priskiriama sudėtingų daugiaaspekčių uždavinių kategorijai (Aissaoui et al 2007;Ho et al 2010;Sanayei et al 2010), neretai įvardijama kompleksiniu uždaviniu, nurodant sudėtinių dalių -dalinių uždavinių rinkinius. Dėl tiekėjų atrankos dalinių uždavinių rinkinio tyrėjų nuomonės įvairesnės.…”

Santrauka. Straipsnyje nagrinėjama tiekėjų atrankos problema. Tiekėjų atranka traktuojama kaip sprendimų ciklas, kuriam būdingos šios fazės: tiekėjų paieška, preliminari atranka, kompleksinis vertinimas, derybos, sutarties sudarymas, tiekimo stebėsena. Dabartinė šios srities situacija apibūdinta taip: didelis verslo praktikos interesas didinti sprendimų, parenkant tiekėjus, pagrįstumą, tyrėjų siūlomų tiekėjų atrankos metodų ir modelių įvairovė ir tik epizodiškas gausaus metodinio potencialo taikymas praktikoje. Padėčiai gerinti siūlome plėtoti tiekėjų atrankos sprendimų intelektinės paramos terpę. Aprašytas siūlomos integruotos sprendimų intelektinės paramos sistemos variantas. Joje integruoti ekspertinės, individualių sprendimų, grupinių sprendimų ir derybų paramos komponentai. Sprendimų turinio ir proceso parama individualizuota atsižvelgiant į tiekėjų atrankos ciklo fazių specifiką.Reikšminiai žodžiai: tiekėjų atranka, atrankos ciklas, daugiakriterinis vertinimas, intelektinė sprendimų parama. Abstract. This paper examines the problem of supplier selection. The supplier selection process has been expressed as decision cycle, which involves such phases: searching for suppliers, preliminary selection, complex evaluation, negotiations, preparing a contract, monitoring. The present situation in this field has been described in such a way: large interest to increase validity of decisions for supplier selection from side of business practice, diversity of methods and models for supplier selection suggested by researchers, the episodic character of putting into practice this methodical potential. In order to improve such a situation, we see a need to develop the medium of intelligent support for supplier selection decisions. The suggested variant of integrated decisions intelligent support system is provided. The components of expert judgment support, individual decision support, group decision support and negotiations support have been incorporated into proposed system. The content and process of decisions support have been specified in accordance with character of every phase of supplier selection cycle. DECISIONS OF INTELLIGENT SUPPORT FOR SUPPLIER SELECTION

“…For reviews on the supplier selection problem, we refer the reader to Benton and Park (1996), Munson and Rosenblatt (1998) and Aissaoui et al (2007). Here we summarize some examples on different variants of the problem.…”

We consider a problem faced by a procurement manager who needs to purchase a large volume of multiple items over multiple periods from multiple suppliers that provide base prices and discounts. Discounts are contingent on meeting various conditions on total volume or spend, and some are tied to future realizations of random events that can be mutually verified. We formulate a scenario-based multi-stage stochastic optimization model that allows us to consider random events such as a drop in price because of the most favoured customer clauses, a price change in the spot market or a new discount offer. We propose certainty-equivalent heuristics and evaluate the regret of using them. We use our model for three bidding events of a large manufacturing company. The results show that considering most favored customer clauses in supplier offers may create substantial savings that may surpass the savings from regular discount offers.

“…Supplier selection has been shown to have a great potential to improve both the buying firm's and the supplier's performance (Monczka et al, 1993;Krause, 1997;Vickery et al, 2003;Li et al, 2012). As such, this area has been researched extensively and we refer the reader to literature reviews focusing on the selection criteria and decision-making process (Weber et al, 1991;De Boer et al, 2001;Aissaoui et al, 2007;Ho et al, 2010;Agarwal et al, 2011), as well as "green" supplier selection (Govindan et al, 2013). Research has begun to shift away from more simple transaction cost economic approaches (Williamson, 1985;Dyer, 1997) and toward social capital theories (Krause et al, 2007;Carey et al, 2011), which capture more of the nuances of the inter-firm dynamics.…”

Recycling procurement strategies with variable yield suppliers

Companies are no longer judged on financial performance alone, but rather on their "Triple-Bottom Line", which accounts for social and environmental measures as well. This leads companies to investigate the sustainability of their operations and their products. Between the increasing cost of virgin raw materials and customers demanding post-consumer product content, manufacturers have begun looking at recycled material options. This paper addresses a procurement issue facing a polystyrene packaging manufacturer considering its optimal purchasing strategies between two suppliers -one providing virgin material, the other offering recycled material. A single-period scenario is modeled where each supplier sells product with a known yield distribution at market pricing. The manufacturer must choose whether to sole-source or dual-source, as well as determine how much material to purchase from each supplier to meet deterministic demand. Our results indicate that there is a range of prices from the recycled material supplier where dual-sourcing will lead to higher manufacturer profits compared to solesourcing. We show, based on the procurement strategy, the optimal quantities to purchase to maximize manufacturer's expected profit.We then investigate the area of supplier development and how the manufacturer can improve their expected profit by investing in their supplier's quality improvement effort. The questions addressed are how much the manufacturer would be willing to invest and how they ensure the proper return on their investment. This paper determines the expected increase in profit for the manufacturer from yield improvement projects at a supplier, which therefore becomes the upper threshold for investment. We also find that a company can err in their project acceptance criteria if they have an approval process that views project acceptance myopically rather than holistically.Lastly, we develop a systematic and comprehensive approach to the supplier selection process. We utilize the fundamental concepts behind W. Edwards Deming's Plan-Do-Study-Act improvement cycle and apply them to the supplier selection process.We also present analytic and numerical study results that can be used in conjunction with contractual mechanisms to not only overcome issues such as free riding, but to also incentivize suppliers to engage in supplier development projects they may not have otherwise undertaken. In order to understand why companies have become more attentive to the issue of recycling, one must look back over the past few decades. Firms have faced increased scrutiny on the environmental impact surrounding the disposal of consumer goods, the disposition of production by-products, and how they act as corporate citizens. No longer are companies judged solely on their financial measurements. They are now being evaluated on the "Triple Bottom Line". This metric measures a firm's social and environmental performance, as well as its economic performance. Manufacturers must 2 now address how their products impact the environment...
