PCB and the Paper Industry—A Progress Report
The paper industry's experiences with PCBs were chronologically reviewed at a recent "PCB Workshop" sponsored by the Grocery Manufacturers of America, Inc. (1). This history goes back somewhat over a year, at which time two paperboard manufacturers were apprised of the presence of PCBs in folding cartons for packaging dried fruit. These two manufacturers immediately began searching for the sour...
متن کاملCollaborative Product Development in PCB Industry
Collaborative product development has become a critical issue for companies to strengthen their core competence and remain competitive in the global market due to the rapid change of global economics. However, most companies have a lack of experience in conducting collaborative design and implementing IT environment that facilitates it. To overcome these deficiencies, this research studies coll...
متن کاملEvolutionary algorithm for PCB scheduling problem
This study focuses on PCB scheduling problem with sequence-dependent setup times on a single machine and feeder capacity constraint. The objective of the scheduling problem is to minimize the total weighted tardiness. The evolutionary algorithms to solve this PCB scheduling problem is an integration of genetic algorithm, local search procedure, heuristic scheduling rule and Keep Tool Needed Soo...
متن کاملA coupling cutting stock-lot sizing problem in the paper industry
An important production programming problem arises in paper industries coupling multiple machine scheduling with cutting stocks. Concerning machine scheduling: how can the production of the quantity of large rolls of paper of different types be determined. These rolls are cut to meet demand of items. Scheduling that minimizes setups and production costs may produce rolls which may increase wast...
متن کاملRheological Issues in the Paper Industry
The paper industry has a number of processes where the rheology is complex and critical to control for trouble free operation. The rheological properties of pulp suspensions and paper coatings are reviewed here. The flow, rheology and other various phenomena are discussed for pulp suspensions. The particle level models that have been developed for pulp suspensions are compared to experimental r...
