In this paper a new bf oriented tabu search version is presented. It can be used to improve arbitrary existing sequential or parallel tabu search procedures for solving especially long-term production planning problems. As an example the Simple Assembly Line Balancing Problem 2 is considered where an eecient tabu search heuristic exists. Although this sequential procedure reach already good res...

A three stage production system is considered in this paper. There are two stages to fabricate and ready the parts and an assembly stage to assembly the parts and complete the products in this system. Suppose that a number of products of different kinds are ordered. Each product is assembled with a set of several parts. At first the parts are produced in the first stage with parallel machines a...

This paper address a special class of generalized assembly line balancing in which it is assumed that there are two groups of workers: skilled and unskilled ones. The skilled workers are hired permanently while the unskilled ones can be hired temporarily in order to meet the seasonal demands. It is also assumed that more than one worker may be assigned to each workstation. To show the adv...

With the growth in customers’ demand diversification, mixed-model U-lines (MMUL) have acquired increasing importance in the area of assembly systems. There are generally two different approaches in the literature for balancing such systems. Some researchers believe that since the types of models can be very diverse, a balancing approach without simultaneously sequencing of models will not yield...

Mixed model two-sided assembly lines (MM2SAL) are applied to assemble large product models, which is produced in high-volume. So, the sequence planning of products to reduce cost and increase productivity in this kind of lines is imperative. The presented problem is tackled in two steps. In step 1, a framework is developed to select and prioritize customer orders under the finite capacity of th...

The paper deals with the modeling of processes charge-discharge battery assemblies taking into account their degradation. results simulating cyclic operation in Electronics Workbench electronic laboratory are presented, possible schemes inclusion given, and options for re-switching batteries during considered as well connecting additional elements to extend life connection. simulation took pres...

Multi-manned assembly line, which is broadly utilized to assemble high volume products such as automobiles and trucks, allows a group of workers different tasks simultaneously in multi-manned workstation. This additional characteristic parallel operators increases the complexity traditional NP-hard line balancing problem. Hence, this paper formulates Type-I problem minimize total number worksta...

This paper presents a new approach for the determination of 3 − RPR planar parallel robot assembly modes. In this approach, the parallel robot is considered as a multi robot system. The segments are then regarded as serial robots moving a common load. The proposed approach is based on a parallel robot Jacobian matrix factorization. This factorization is an extension of global formalism develope...
