The concept of limited #exibility, originally applied to production planning, has shown that many bene"ts of totally #exible systems can be obtained by less #exible systems. This concept is here applied to shop #oor control. Limited #exibility is considered as a particular routing #exibility that allows system resources to process some products according to a logic chain, as an intermediate con...

In this paper we introduce a new class of queueing networks called arrival first networks. We characterise its transition rates and derive the relationship between arrival rules, linear partial balance equations, and product form stationary distributions. This model is motivated by production systems operating under a kanban protocol. In contrast with the conventional departure first networks, ...

The freshness of perishable products, in addition to other economic aspects such as production, inventory, and transportation management, is one the main challenges food supply chains. Therefore, integration routing decisions essential. In this study, a new production model for products with uncertain demand presented. aim minimize costs routing, wasted penalties non-fresh products. more applic...

We consider a biodiesel production company that collects waste vegetable oil from source points that generate waste in large amounts. The company uses the collected waste as raw material for biodiesel production. The manager of this company needs to decide which of the present source points to include in the collection program, which of them to visit on each day, which periodic routing schedule...

The single vehicle routing problem with multiple routes is a variant of the vehicle routing problem where the vehicle can be dispatched to several routes during its workday to serve a number of customers. In this paper we propose a goal programming model for multi-objective single vehicle routing problem with time windows and multiple routes. To solve the model, we present a heuristic method wh...

The availability of inexpensive wireless networking hardware (e.g., based on the IEEE 802.11 standards) has generated interest in a large class of wireless applications. Many applications benefit from rapidly deployable networks—for example, collaborative applications to support field research or emergency incident response. The need for networks that can be rapidly deployed has resulted in a s...

Abstract Maritime inventory routing problems with load-dependent speed optimization involves determining optimal routes, as well vessel speeds and loads at these so that limits are satisfied both production consumption ports. This paper considers a variant where rates can be selected from several available alternative levels, opposed to the normal situation chosen priori. In cases, remain const...

• A new supply chain concept based on the idea of mobile (moveable) factory. mathematical model for chains. Matching batching, production, and factory routing activities. multi-objective approach a multi-agent problem. Many chains suffer from lack flexibility, adaptability, robustness, which imposes customer dissatisfaction, transportation, backlog, rework costs companies. The (MSC) is newly de...
