“…The use of evolutionary algorithms (EA) in scheduling possesses significant potential for solving manufacturing control problems. Käschel et al (2002) introduced an evolutionary search algorithm for shop floor scheduling and integrated the scheduler with a bidirectional plant data acquisition (PDA) system used for data collection as well as distribution of sequencing information. The authors reported a quality improvement of evolutionary tools by separating the time-consuming scheduling procedure from the EA.…”

Purpose -As the manufacturing activities in today's industries are getting more and more complex, it is required for the manufacturing firm to have a good shop floor production scheduling to plan and schedule their production orders. An accurate scheduling is essential to any manufacturing firm in order to be competitive in global market. The paper aims to discuss these issues. Design/methodology/approach -Two types of shop floors, job shop and cellular layout, were developed by using WITNESS simulation package. Consequently, the performance of forward scheduling and backward scheduling in both job shop and cellular layout was compared using simulation method, and the results were analyzed by using analysis of variance (ANOVA). Through analysis, the best scheduling approach and layout to be used by manufacturing firm in order to achieve the make-to-order (MTO) production and inventory strategy were reported. Findings -The results from simulation show that backward scheduling in job shop layout has the lowest average throughput time, lowest lateness, and highest labour productivity than forward scheduling. While in cellular layout, forward scheduling has the lowest average throughput time, lowest lateness, and highest labour productivity than backward scheduling in all conditions. It shows that the performance of scheduling approach is different in each production layout. Originality/value -Suitable scheduling approach is needed in manufacturing industry as to maximize production rate and optimize machine and process capability. This paper presents an empirical study about the assembly process of radio cassette player of one manufacturing industry in order to investigate the impact of variety of orders and different number of two workers on the performance of production scheduling approach. Forward scheduling and backward scheduling are used to schedule the production orders.

“…The principles of the Plan, Do, Check, and Action (PDCA) are important parts of the ISO 9000 standard, which requires organizations to improve quality continuously. Since a QAS requires managing process and related document/data, using a technology such as RFID can enhance the effectiveness of the system and ultimately provide a capability for preventing defects via data analysis (Käschel, Teich, & Zacher, 2002).…”
