this paper aims to investigate the integrated production/distribution and inventory planning for perishable products with fixed life time in the constant condition of storage throughout a two-echelon supply chain by integrating producers and distributors. this problem arises from real environment in which multi-plant with multi-function lines produce multi-perishable products with fixed life ti...

In recent years, the value-added created in the transportation industry is about 8 percent of GDP of Iran. Due to the high-induced effect of transportation sector on the whole economy, analyzing transportation production function and its determinant is of great value for policymakers. The objective of the present research is to estimate the transportation production for the case of Iran and to ...

The Trans-Texas Corridor (TTC) projects a vision of 4000 centerline miles of new roadways and railways, intended to provide a faster, safer and more reliable means of transport for people and freight, while fostering economic growth of Texas’s rural regions. This work enhances and then applies a Random-Utility-Based Multiregional Input-Output (RUBMRIO) model to assess project impacts on trade, ...

this paper is focused on the tactical design of steel supply chain (ssc). a general mathematical model is proposed to integrate production and transportation planning in multi-commodity ssc. the main purpose is to prepare a countrywide production and distribution plan in an ssc with three layers consisting of iron ore mines as suppliers, steel companies as producers, and subsidiary steel compan...

In this paper we consider the problem of planning the production and distribution in a supply chain. The situation consists in a set of distribution centers seeking to serve to a set of retailers; these distribution centers are supplied by a set of plants trying to minimize the operation and transportation costs. The problem is formulated as a bilevel mathematical problem where the upper level ...

Ongoing globalization causes increasing transportation rates and transshipment volumes at sea ports (Steenken, 2004). Different to container transshipment, the transshipment of finished vehicles has received only minor attention in research yet (Mattfeld and Kopfer, 2003). By means of statistics for major ports of the North-West European coast line the structure and development of vehicle trans...

Improvements in technology and logistics practices have radically altered distribution chains. More efficient and less expensive transport, communication, and information systems have fuelled the extension of supply chains and the globalization of the world economy. At the micro-level, companies have become increasingly customer-orderdriven. Production systems such as JIT, Lean Production, or T...

Managers are increasingly realizing the value of integrating production and logistics management at the same time as third-party logistics contracting is becoming a more widely utilized practice across many industries. Motivated by this observation, we first review a variety of models that focus on integrated production/distribution systems, and then develop models to analyze the optimal operat...
