A payment cost minimization (PCM) auction has been proposed to solve the problem of inflated wholesale electricity prices. In the electricity industry, where even small changes in $/MW are worth tens of millions of dollars, it is highly important that policy makers have a good understanding of the tradeoffs and impacts of new institutional rules. In this paper we examine efficiency performance ...

Existing Sustainable Supply Chain Management frameworks attempt to incorporate each tier of the end-to-end supply chain. However, the firm or buyer-supplier dyad is predominately used as a unit of analysis, leaving a gap regarding how indirect suppliers affect firm sustainability. To fill this gap we pose two research questions: What role do indirect suppliers play in firm sustainability? And; ...

Supplier selection is a multi-Criteria problem. This study proposes a hybrid model for supporting the suppliers’ selection and ranking. This research is a two-stage model designed to fully rank the suppliers where each supplier has multiple Inputs and Outputs. First, the supplier evaluation problem is formulated by Data Envelopment Analysis (DEA), since the regarded decision deals with uncertai...

In this paper, we study an outsourced supply chain consisting of one buyer and two suppliers in which the buyer outsources manufacturing of a physical product to two competing suppliers. The suppliers compete for the buyers' demands share, and the buyer allocates the demands to the competing suppliers based on three-dimensional allocation functions. We consider two certain types of allocation f...

Nowadays companies measure suppliers on the basis of a variety of factors and criteria that affect the supplier's selection issue. This paper intended to identify the key effective criteria for selection of green suppliers through an efficient algorithm callediterative process mining or i-PM. Green data were collected first by reviewing the previous studies to identify various environmental cri...

In this paper, the authors analyze 91 key account relationships and 206 ordinary supplier–buyer dyads regarding differences in suppliers' relational behaviors and customers' perceptions of relationship quality (satisfaction, trust, and commitment). The results suggest that while – as compared to ordinary relationships – suppliers put significantly more effort in “value-creating behaviors” in ke...

Supplying chain cooperation has already become an important strategy that enterprises use to tackle market competition; however, the supply chain crisis caused by supply chain risk makes the supply chain operation of enterprises very fragile. This paper applies Portfolio Theory to explain the suppliers’ combination plays an important role in dispersing the supplying chain risk and controlling i...

kecarassembly plants which have adopted `lean production' trading with `lean' parts suppliers? Or are they using suppliers as buffers and as sources of low cost labour? This paper examines these questions empirically by using official statistics in the UK, US, Germany and Japan. In the UK, there is evidence of parallel reduction in inventories at suppliers and assemblers in the 1980s, but also ...

The main purpose of this chapter is to develop an exploratory proposal for identifying innovative suppliers, creating knowledge in an area not very deeply explored. Based on a literature revision based on the innovative supplier identification and management, the study suggests that innovative suppliers are highly specialized and technically competent companies, located nearby their customers a...

Evaluation of biomass suppliers is a time-dependent problem that requires assessment of different supply schemes in different periods. This paper presents a hybrid method for evaluating biomass suppliers that combines Intuitionistic Fuzzy Sets (IFS), linear programming (LP) and multi-periodic optimization (MPO). IFS allow evaluators to express their hesitation when they assess alternative suppl...
