ARRANGING PRECAST PRODUCTION SCHEDULES USING

2014-3-31  Precast construction is a method to build up constructions by prefabricated concrete elements (Demiralp et al. 2012). Precast fabricators deliver elements to construction site according to its erection schedule. Building up constructions using precast elements can reduce uncertainty than those casted in the construction site. In addition, it fits in with the needs of industrial process. As a result, precast fabrication in the construction industry can be categorized as manufacturing (Hossain and Ozyildirim 2013). Production scheduling is one of the most important tasks in the manufacturing. Different production schedule can induce different throughput. Industrial engineers therefore endeavor to finish products with

Precast production scheduling using multi-objective ...

2011-7-1  This research develops a multi-objective precast production scheduling model (MOPPSM). In the model, production resources and buffer size between stations are considered. A multi-objective genetic algorithm is then developed to search for optimum solutions with minimum makespan and tardiness penalties. The performance of the proposed model is validated by using five case studies. The experimental results show that the MOPPSM can successfully search for optimum precast production schedules ...

Production Scheduling for Precast Plants using a Flow

2000-10-20  Abstract. There are two alternatives for production organization in precast factories—namely, the comprehensive method and the specialized method. Production scheduling under the specialized alternative has been found to be a difficult optimization problem if heterogeneous elements are involved. A flow shop sequencing model that incorporates actual ...

PAPER OPEN ACCESS Scheduling the Production of

The optimization model of the precast production described in the paper is as follows: Parameters: • The project consists of a set of precast components: Z = {Z1, Z2, Z3, ..., Zj, ..., Zn}. (1) • For the execution of the works in the precast production, there are teams of working groups created, each of which performs one type of work.

Constraint Programming Approach to Precast

2000-7-17  Current scheduling practices in precast plants are fairly basic and depend greatly on experience. This may lead to inefficient resource utilization, over-inventory, and/or missing delivery dates. Computer assisted scheduling may therefore be useful in producing better production schedules.
