“…Resilience tires are used for heavy trucks, military vehicles, and construction machinery; press-on tires are widely used in airport ground support equipment; non-marking tires are used for pharmaceutical, food, paper, and textile manufacturing facilities (Bandara et al, 2021). Resilience tires consist of three rubber compound layers: base, cushion, and tread (Premarathna et al, 2021). The inner base layer is made of a hard rubber compound that improves the grip contact between the tire and the rim.…”

“…The outer tread layer is made of an abrasion-resistant rubber compound that enhances tire durability and traction. The middle cushion layer is made of a soft rubber compound to absorb shocks and manage heat build-up (Premarathna et al, 2021;Sri Lanka Export Development Board, 2022). Press-on-band tires are made by bonding and pressing rubber compounds to a mild steel band to fit the wheel (Wattegedara & Egodage, 2018) (Newsmantraa, 2022).…”

Businesses are constantly making productivity improvements to survive in the highly competitive marketplace. Bottlenecks have been identified as one of the main factors limiting the system performance of manufacturing firms. Thus, identifying bottlenecks in the production process is extremely important to increase productivity. Considering its importance, this case study was designed to identify causes for not meeting the tire target and determine the implications of bottlenecks in the tire manufacturing process. For this purpose, simulation analysis was carried out for the solid resilience tire-building process. Through the investigation, the cushion layer-building process was identified as the bottleneck. To validate the identified limitation, Line balancing and Pareto analysis were conducted. Analysis results confirmed the presence of a bottleneck in the cushion layer-building process. Further, to identify the root causes for not reaching the maximum tire target, Cause-and-Effect analysis and 5WHY analysis were adopted. The study revealed that inadequately maintained outdated machines and frequent power failures are the leading causes of not meeting the maximum production. By answering these issues, the target production can be increased, and the results showed the opportunity to increase the efficiency of the manufacturing process by more than 95%.
