However, IS Success Model does not fully address how users perceive value of an information system. It assumes that the information quality, system quality, and service quality automatically generate user satisfaction. Users will not be satisfied with information s...

This article develops a supply chain coordination model with a single-vendor and a single-buyer. The vendor manufactures the product in lots and delivers to the buyer in equal shipments. However, the vendor’s production process is not perfectly reliable. During a production run, the process may shift from an in-control state to an out-ofcontrol state at any random time and produces some defecti...

This paper makes an analysis on a default swap option that an investment bank in Japan produced on the credit-risk of a convertible bond issued by a third company C. In this default swap option, a protection buyer A against a default of C owns the right of starting an interest swap between the buyer and a protection seller B when a credit event happens. When B starts the swap after a default, t...

Coordination models have been developed to optimize the entire supply chain and align the decisions between its entities.

one of the most important problems of the designs proposed by traditional economic-statistical approaches of control charts is inefficiency in the face of uncertainty. uncertainty in the parameters of economic-statistical models may lead to failure in rapidly detecting changes in processes and impose greater costs to the organization. monitoring the machining process in an automotive industry e...

In this paper we conjugate the operative usability of the net present value with the capability of the fuzzy and the interval approaches to manage uncertainty. Our fuzzy interval net present value can be interpreted, besides the usual present value of an investment project, as the present value of a contract in which the buyer lets the counterpart the possibility to release goods/services for m...

Packer upstream integration is linked to the need to align packer-producer investment incentives in an environment marked by increasing hog buyer consolidation, changing consumer demands, moves toward traceability in the ...

We model new experience goods in the context of dynamic mechanism design. These are goods for which an agent is unsure of her valuation but can learn it through consumption experience. We consider a dynamic environment with a single buyer and seller in which contracting occurs over T periods, where each time the agent consumes the object, she receives a signal which allows her to revise her val...
