The supply chain of a manufacturing enterprise is a world-wide network of suppliers, factories, warehouses, distribution centres and retailers through which raw materials are acquired, transformed and delivered to customers. Supply chain management is the strategic, tactical and operational level decision making that optimizes supply chain performance. The strategic level defines the supply cha...

Recently, there has been a growing interest in reverse logistics due to environmental deterioration. Firms incorporate reverse flow to their systems for such reasons as ecological and economic factors, government regulations and social responsibilities. In this paper a new mixed integer mathematical model for a remanufacturing system, which includes both forward and reverse flows, is proposed a...

There is still very limited information on the physical and chemical properties of dried distiller’s grain with solubles (DDGS) derived from wheat-based fuel ethanol production. As this coproduct become increasingly more available in Western Canada, baseline information on its properties is essential in responding to problems posed by existing processing, handling, storage, and transportation s...

A two-level transportation system with scheduling of independent, non-preemptive tasks on unrelated moving executors as well as motion control of a group of moving executors performing the tasks is considered. It is substituted by an uncertain one-level system, where execution times of the tasks are not crisp values but they belong to known intervals. In order to solve the problem the robust ap...

For manufacturing industries, the integration of business processes from customer-order management to delivery (Supply Chain Management) has widely been received much attention from the viewpoints of agile and lean manufacturing. Supply chain planning concerns broad activities ranging network-wide inventory management, forecasting, transportation, distribution planning, production planning and ...

Hardly any economist or economic historian now disputes that technical progress and advances in scientific knowledge underpin all long-term, sustained economic growth. Sure, in the short run, sharp spurts of improvement in economic performance can arise from investing in factories, streamlining transportation and distribution networks, bettering market structure, and removing impediments to pro...

The world economics are developing to the internationalization direction depth, various countries' economy in interdependence and under international division of labor condition, not only in production, distribution area, but also in the capital, technology, information, and transportation and so on, manifests internationalization tendency. In order to deal with the international market and the...

In this paper, we deal with the production and transportation planning of a household appliances manufacturer that has production facilities and central stores for resellers in several sites in Europe. Each store can receive products from all production plants and it is not necessary that all products are produced in all production units. The transport between any two bases is done by trucks. F...

A brief history of transportation and the environment The relationship between transportation, technology and the environment is long standing. In the early 1920s, the car was first viewed as an improvement over the horse-polluted city environment. By the early 1930s, interest in an Interstate Highway System grew as a means to help get cars and trucks out of the mud. But, as automobile ownershi...
