This book was released on 1991 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of this thesis is the minimization of the sum of absolute deviations of job completion times from a common due date for the two machine flow shop scheduling problem (2SADD). The problem is mathematically formulated as a mixed integer program. The purpose of this research is the development of heuristic procedures to solve the 2SADD scheduling problem. The heuristic procedures provide a sequence which is solved for the optimal schedule using linear programming. The solutions of the heuristic procedures are compared against the optimal solutions for data sets with five and six jobs. The three best performing heuristic procedures are compared against each other using data sets with ten, fifteen, and twenty jobs. The recommendations of this research are to 1) use the optimal solution for the special case of a distant due date (greater than the sum of all processing times), 2) use Bagchi/Pairwise Interchange Heuristic for small numbers of jobs (less than ten), 3) use One-By-One/SPT and One-By-One/LPT for a number of jobs of ten or greater.

Available in PDF, EPUB and Kindle. Book excerpt: "An important aspect of any manufacturing environment is efficient job scheduling. With an increase in manufacturing facilities focused on producing goods with a cellular manufacturing approach, the need arises to schedule jobs optimally into cells at a specific time. A mathematical model has been developed to represent a standard cellular manufacturing job scheduling problem. The model incorporates important parameters of the jobs and the cells along with other system constraints. With each job and each cell having its own distinguishing parameters, the task of scheduling jobs via integer linear programming quickly becomes very difficult and time-consuming. In fact, such a job scheduling problem is of the NP-Complete complexity class. In an attempt to solve the problem within an acceptable amount of time, several heuristics have been developed to be applied to the model and examined for problems of different sizes and difficulty levels, culminating in an ultimate heuristic that can be applied to most size problems. The ultimate heuristic uses a greedy multi-phase iterative process to first assign jobs to particular cells and then to schedule the jobs within the assigned cells. The heuristic relaxes several variables and constraints along the way, while taking into account the flexibility of the different jobs and the current load of the different cells. Testing and analysis shows that when the heuristic is applied to various size job scheduling problems, the solving time is significantly decreased, while still resulting in a near optimal solution "--Abstract.

Download or read book Development and Experimental Evaluation of Branch and bound Algorithms for Determining Optimum Static Job shop Production Schedules written by P. Rama Ramalingam and published by . This book was released on 1972 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: Branch-and-Bound algorithms are developed to optimally schedule static single- and multi-stage job-shop productions. The 'corollary' of the study is to experimentally verify the effectiveness of branch-and-bound algorithms to overcome the "curse of dimensionality" due to the combinatorial nature of job-shop scheduling problems. The static scheduling problem contemplated in this dissertation assumes that for the given set of n jobs, their deterministic processing times, relative due dates and monotonically decreasing bonus and penalty functions are known. The effectiveness of the selected schedule is evaluated from the total revenue obtained from the bonus and penalty. Based on the branch-and-bound algorithms, two computer programs have been written in FORTRAN IV and their processing times on CDC-3300 recorded. Thirty single- and thirty three-stage problems ranging in size from five to ten jobs were solved. Their CPU times were from a few seconds to four minutes. Regression models were developed to predict both the CPU time and the number of nodes computed by the basic branch-and-bound method. It is predicted that in an eight-hour CDC-3300 CPU time, one single-stage problem with up to 21 jobs can be solved. In this same time duration, the exhaustive search program will not have processed a single-stage problem with more than eight jobs. Two variations of the basic algorithm have been considered: the heuristic near-optimum method and the dominance-tested computational procedure. The heuristic method requires the least computational effort and is a practical scheduling tool for large-size problems, but does not guarantee the optimality of its solution. By applying the dominance-tested variation, the optimum solution can be assured. It requires the generation of a fewer number of nodes than the basic branch-and-bound technique, yet it needs a significantly larger computational time. The basic branch-and-bound algorithm's application to non-job- shop scheduling situations has been illustrated by two examples: the determination of the optimum distribution policy in a marketing study, and of the optimum routing schedule for a fishing vessel harvesting operation. The experimental data verified that branch-and-bound algorithm has been only partially successful in overcoming the "curse of dimensionality." The inherent combinatorial difficulty is still present in the branch-and-bound algorithm though to a lesser degree than in dynamic programming--and a more powerful optimization method must be developed to limit the size of the solution space at an early stage of analysis.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis, based on an industry problem, looks at the job-shop scheduling problem from a project planning and scheduling perspective. The job-shop has two types of re- sources, namely operators and machines and involves generalized precedence relations arising from part routings. In addition, the job-shop environment has other considera- tions such as project priority, alternative resources, and partial resource usage. An integer linear programming with binary variables is developed for the job-shop with the above features in mind considering two objectives. This model can be used at two different hierarchical production planning levels, namely for high level planning and detailed scheduling. The higher level planning of the model is aimed at upper management in the job-shop who can use it for aggregate purposes such as resource allocation, customer order promising, due-date planning, and material procurement. On the other hand, the detailed scheduling is targeted towards production managers and is used to develop detailed short-term operation schedules. The model outcome on a real world problem has been compared with some well-known huristic methods.
