In recent years interorganizational communication and coordination have relied increasingly on the exchange of EDIFACT-messages. Unfortunately, coordination protocols based on EDIFACT are typically complex. As a consequence, coordination by EDIFACT requires a close coupling and a huge amount of messages to be pro table. In the logistics sector Tracking and Tracing based on EDIFACT led to in exi...

In this study, a two-echelon supplier-manufacturer system with finite production rate and lead time is proposed. It is assumed that shortage is not permitted and the lot size of manufacturer (second echelon) is m-factors of the lot size of supplier (first echelon) and supplier can supply the manufacturer’s lot size in several shipments in each cyc...

To examine the role of international competition in outsourcing production decisions, I study the decisions of producers who used the U.S. Overseas Assembly Program (OAP) to conduct assembly operations in developing countries. The evidence, which is based on U.S. OAP imports between 1991 to 2000, shows that production costs and corporate tax policies both shaped production decisions. While incr...

Allocating inspection resources over a diverse set of imports to prevent entry of plant pests and pathogens presents a substantial policy design challenge. We model inspections of live plant imports and producer responses to inspections using a “state-dependent” monitoring and enforcement model. We capture exporter abatement response to a set of feasible inspection policies from the regulator. ...

In this paper, we developed a supply chain network game theory model with differentiated products and transportation costs in the case of time-based oligopolistic competition. The firms are profit-maximizers and have, as their strategic variables, the product shipments and the guaranteed delivery times to the consumers at the demand markets with the guaranteed delivery times never exceeding the...

Mobility is one of the trends in 2014. According to the report of IDC (International Data Corporation), the worldwide shipments of tablets have exceeded PCs in 2013 Quarter 4, while smart phones has already exceeded other devices in unit shipments and market ratio. With this trend, many location-based services (LBS) have been proposed, for example, navigation, searching restaurants or gas stati...

This paper presents a research study which aims at determining optimal locations of regional distribution centers in a collaborative distribution network. We consider a multi-layered distribution system between a cluster of suppliers from a given region and several thousands customers spread over the whole country. The optimization problem consists of finding the locations of intermediate logis...
