“…Ammons et al [8] continue the work by considering component allocation to two or more placement machines, when the objective is to balance a combination of the assembly time and the machine setup time. When machines are coupled, the workload balancing reduces to maximizing the throughput of the bottleneck machine on line.…”

“…Because these goals are contradictory, the presented model tries to minimize the setup costs while keeping the workload within prespecified limits. A partial setup (which should not be confused with the partial setup strategy of Leon and Peters [74]) comprises permanent and temporary components (i.e., a standard and custom setup [8]). The authors argue that this partial setup is a compromise between "complete" (i.e., unique) and "incremental" (i.e., minimum) setup, because it reduces setup operations by exploiting component commonalities and is easier to handle than incremental setups.…”

Electronics industry is a major part of modern manufacturing, and electronic systems play an increasingly important role in a majority of today's products. Electronic systems are usually implemented with printed circuit boards (PCBs), and, consequently, PCB assembly has become an important sector of the electronics manufacturing industry overall. However, operating effectively in this industry is becoming more difficult as the companies must compete with high quality standards, rapidly changing technologies, short production cycles, and increasing product variety and complexity. In addition, the capital equipment cost of electronics assembly industry facilities are high in comparison to the usual turnover of a company. As a result, production planning decisions need to made more and more frequently due to continuous changes in the production conditions.In this work we discuss production planning in electronics assembly-and, in particular, in PCB assembly. Our intention is to identify the typical problems arising from production planning and to give a survey of the solution methods suggested in the literature. In addition to this theoretical perspective, we will briefly review applications designed for production planning in PCB assembly.This work is organized as follows: We begin with an introduction to flexible manufacturing systems in general and present a framework for production planning systems in Section 1. Next, we study the fundamentals of PCB assembly process in Section 2 and survey the relevant literature in Section 3. In Section 4 we review existing commercial applications for production planning, and in Section 5 study more closely one of these systems. Finally, in Section 6 we sum up the discussion and outline few important topics for the future research.

In flexible manufacturing systems (FMS) the interaction between the production planner and the scheduling system is essential. This is a typical situation in printed circuit board (PCB) assembly. We discuss the structure and operation of an interactive scheduling system for surface mount component printing involving multiple criteria. The user can compose a schedule by using a heuristic algorithm, but the schedule can be manipulated also directly via a graphical user interface. In addition to system description, we present statistical data of the effect of the system in an actual production environment.

Generalized Flexible Flow Line (GFFL) is a scheduling environment comprising several machine banks which the products visit in the same order but can skip some machine banks. The products are transported either in magazines or by a conveyor belt, and the change of the products demands a set-up operation of the machine. The time consumption of this operation depends on the current and the next product to be processed. This paper describes several scheduling algorithms for GFFL problem. The overall structure of these algorithms is similar, consisting of machine allocation and sequencing phases. The algorithms have been implemented and integrated into an interactive production scheduling system for electronic assembly. Sample cases are used to illustrate the operation of the system in practice.
