Abstract

This Paper Company is a manufacturing company at the field of thin paper industry. At the beginning, this company did not have the quality assurance to final product which has the standard of the quality management system. This study represents that the company doesn't have the Quality Plan to the product. The Quality Plan become the main concern to assure the product quality until they are distributed to the customer. This study is meant to design the Quality Plan for the company management system. It will be divided into three parts; first, the inspection of the raw and chemical materials, second, the inspection of the production process, and the final is the inspection of the output jumbo roll. This first inspection is done five times, the second inspection will done in twelve times, and the final process will be done in one process only.

Abstract

The problem faced by company is the difference in PPIC Department between actual result and planned result. The second problem is the low efficiency in bush forming and pin cutting area. Related to that problem, company asked to researcher to do a research on current total workers composition whether it's suitable or not. The method used in this research is standard work combination sheet. The current total workers in bush forming and pin cutting area is proper enough, each area with one operator and one supporter to help both area. The first improvement to do is to divide the task and to shift the role between operator and supporter. Workers with high ability work as supporter to fix machines and workers with moderate ability work as operator. The second improvement is to revise work motion for bush forming and pin cutting operator to be more efficient in movement and time.

Abstract

The article discusses the measurement model of tourism destination images perceived by travellers based on five dimensions of the service quality, i.e. tangibles, reliability, responsiveness, empathy, and assurance. Measurement problems occur when a traveller assesses the quality of a tourism destination service subjectively with vague boundaries and perceives the image of a tourism destination to vary. To address these issues, we designed an inference model using Mamdani's fuzzy inference system. The results of this study are quantitative assessments of the image of tourism destinations by various travellers based on qualitative perceptions of the quality of service experienced by the traveller.

Abstract

This study develops an incentive mechanism model for outsourced personnel in product quality inspection, based on a principal-agent relationship. The core challenge lies in misaligned incentives, where agents often prioritize output volume over quality. By integrating Mechanism Design Theory (MDT) and Linear Programming (LP), our model aligns the principal's objective of minimizing defective products with the agent's utility maximization, subject to Incentive Compatibility and Individual Rationality constraints. Our analysis reveals that the optimal incentive structure combines a basic wage with a performance-based bonus. The optimal effort level of outsourced personnel increases with both rising losses due to defective products and enhanced detection effort effectiveness. The model also shows that optimal inspection allocation should be assigned to personnel with higher capabilities, especially for high-risk products. This research provides a theoretical contribution by integrating MDT and LP for incentive design and offers practical implications for improving product quality through a measurable incentive framework.
