“…For the relative importance of the various elements of the job, each element is assigned a "weight" that defines its importance relative to the others. Weights are defined as the sum of the operating time required for the element and the total operating time required for all elements to replace the elements [15]. Subject to work station priorities, storefronts are assigned according to weight; A job station with a higher weight will start working sooner than one with a lower weight.…”

The purpose of this paper is to determine the number of proposed work stations based on Rank Positional Weight and to find out the results of the comparison between the initial work station conditions and the proposed work station conditions. The method used in optimizing Line Balancing is the Rank Positional Weight (RPW) method by calculating the amount of processing time, Balance Delay, Smoothness Index, the largest track efficiency, and station efficiency. The results of the comparison between the initial work station conditions and the proposed work station conditions using the RPW method in the total production process time of the S11038Z section from the initial conditions of 1060.23 seconds after analysis using the RPW method obtained a shorter processing time of 970.23 seconds or reduced by 90 seconds. The balance delay in the initial condition was 67.6% with the RPW method, the result was that the balance delay was better, namely 62.9%. The smoothness index in the initial conditions is 1059.79 to 857.88. The tracking efficiency increased by 4.7%, from 32.4% to 37.1%. The efficiency of the biggest workstations also increased, from 489 seconds to 399 seconds.

“…One of the most common system used by manufacturing companies [31,32] is the assembly line system. The assembly line system is widely applied in manufacturing automobile [33,34], computer, electronic equipment [35] and others. However, there are two major problems faced by the companies when using the system; the bottleneck and the idle time [36].…”

<p>Currently, problem in assembly line has created so much attention, particularly in manufacturing area. Similar to this case study as they faced with problems regarding workstation in production line of electrical industry. There exist some cases where workstations in assembly line are experienced with bottleneck and suffered from high idle time. Thus, four heuristic methods are used for minimizing number or workstations and improve the bottleneck problems at the same time. In this case study, LCR, RPW and LPT have successfully minimized the number of workstations from 19 to 16. This solution has affected the layout of assembly line. Different from SPT that manage to improve the bottleneck among workstations by reducing number of workstations from 19 to 17 without changing the line layout. Therefore, both solution has brought an option for an engineer to choose which decision to be used in this assembly line in order to increase the line efficiency.</p>

“…First, Ranked Position Weight (RPW) is chosen. This method has been widely implemented and proven to solve cases for line balancing (Hegelson & Bernie, 1955;Deshpande & Joshi, 2007;Hamzas et al, 2017;Alif & Aribowo, 2019). Secondly, the Region Approach (RA) heuristics was suggested by Bedworth & Bailey (1987) as an improvement based on the RPW method.…”

This paper explains the improvement of PT ZYX's productivity on the assembly line-A, using the production line balancing method. Four methods of line balancing were examined, namely, Ranking Positional Weight (RPW), Region Approach, J-Wagon and Kaizen. The selection of the most suitable method is made based on the reduction of number of workstation and cycle-time. Based on the result. Kaizen method shows better total cycle time, number of workstation, and number of operator required. This result is simulated using the 'Tecnomatix' software with the DES (Discrete Event Simulation) method.
