An adaptive k-out-of-N Priced Oblivious Transfer (POT) scheme is a two-party protocol betweena vendor and a buyer. The vendor sells a set of messagesm1, . . .,mN with pricesp1, . . . ,pN . Ineach transfer phase i = 1, . . . , k, the buyer chooses a selection value σi ∈ {1, . . . ,N } and interactswith the vendor to buy messagemσi in such a way that the vendor doe...

The current infrastructure for Web services supports service discovery based on a common repository. However, the key challenge is not discovery but selection: ultimately, the service user must select one good provider. Whereas service descriptions are given from the perspective of providers, service selection must take the perspective of users. In this way, service selection involves pragmatic...

Taking a social shaping perspective we unpack the development trajectory of a packaged software product to show, that contrary to mainstream accounts, design is not completely specified a-priori and that the process continues throughout implementation, and use. We show how developers, in this case third party vendors, can continue to engage in shaping packages during implementation and also how...

Multicriteria decision making (MCDM) has found many applications in both public and private sector organizations. MCDM is both an approach and a set of techniques, with the goal of providing an overall ordering of options, from the most preferred to the least preferred option. The set of MCDM techniques are implemented in selecting the vendors and 3PL service providers. Supplier selection is a ...

Vendor performance plays a key role in price, quality, timely delivery and service in achieving the goals of the supply chain. Given this, today's supplier performance has become a critical element in the success or failure of a company. In this study, an idealized planning model with multi-criteria decision-making approach with network analysis tool based on the expansion of fuzzy quality func...

Selection and negotiation of purchasing bids is a complex decision making process that requires consideration of a variety of vendor attributes such as price, delivery performance, and quality. Although several decision models have been utilized for vendor evaluation and selection, this paper proposes a buyer–seller game model that has distinct advantages over existing methods for bid selection...

This study consists of three types of vendor selection models in supply chains and presents a decision making scheme for choosing appropriate method for supplier selection under certainty, uncertainty and probabilistic conditions. These models are, Data Envelopment Analysis (DEA), Fuzzy Data Envelopment Analysis (FDEA), and Chance Constraint Data Envelopment Analysis (CCDEA). In FDEA model we u...
