in this paper, the study deals with the lead time and setup reduction problem in the vendor-purchaser integrated inventory model. the cost of capital (i.e., opportunity cost) is one of the key factors in making the inventory and investment decisions. lead time is an important element in any inventory system. the proposed model is presents an integrated inventory model with controllable lead tim...

In this work we further enhance the work of Aiello et al. [1] on priced oblivious transfer, in which selling digital goods based on oblivious transfer is discussed. Their primary goal is to mimic a scenario in which a customer is buying digital goods from the vendor where the privacy of the customer is fully protected regarding which item(s) are bought or what is the total amount of shopping. N...

there are many benefits for coordination of multiple suppliers when single supplier cannot satisfy buyer demands.  in addition, buyer needs to purchase multiple items in a real supply chain. so, a model that satisfies these requests has many advantages. we extend the existing approaches in the literature that assume all suppliers need to be put on a common replenishment cycle and each supplier ...

How do the coordination mechanisms evolve during a project, and why? Coordination mechanisms were classified into standards, plans, formal mutual adjustment, and informal mutual adjustment. Two studies were conducted, including s...

In this paper, we study demand disruption in service supply chain with a client and a vendor. We find the positive demand disruption worse off the double marginalization under wholesale contracts. To address the challenge, we propose a two-part tariff contract under which, the client pays the vendor a fixed fee besides the wholesale price if the service rate was met. The results show the channe...

Organizations are pursuing the outsourcing of business processes (BPO) to offshore locations. However, current research has shown that a knowledge-sharing gap between the client and vendor organizations leads to less than expected benefits. This research applies social capital theory to study the antecedents necessary for the creation of social and intellectual capital in the BPO relationship a...

  Most supplier selection models consider the buyer’s viewpoint and maximize only the buyer’s profit. This does not necessarily lead to an optimal situation for all the members of a supply chain. Coordination models have been developed to optimize the entire supply chain and align the decisions between its entities. Little research has been done on the application of these models in the supplie...

Vendor managed inventory (VMI) agreements are a supply chain collaboration principle in which the supplier is responsible for keeping at buyer between given lower and upper limits. VMI gives lot of autonomy while making replenishments, allowing to efficiently ensure availability buyer. But different suppliers may apply approaches staying limits under VMI. Relatedly, objectives not completely al...
