Integration Dematel and ANP for The Supplier Selection in The Textile Industry: A Case Study

Currently, companies are required to improve supply chain performance. One of the main problems in the supply chain is the proper supplier selection. Supplier selection has an essential role in improving supply chain management performance. Supplier selection requires the proper criteria. However, the relationship between criteria is rarely considered in the selection of suppliers in the textile industry. This study tries to propose integrating the Decision Making Trial and Evaluation Laboratory (DEMATEL) and the Analytic Network Process (ANP) for supplier selection in the textile industry. Both methods are multi-criteria decision making (MCDM) tools DEMATEL is used to assess the relationship between criteria. Furthermore, ANP is used to evaluate and weigh the importance of criteria and suppliers. A case study was carried out in a textile company located in Indonesia. The results show that this procedure can identify the relationship and effect of each criterion. The results show that the product price criteria are the criteria that have the most significant weight. The criteria for conformity to specifications and consistency of quality are in second and third place. Finally, suppliers are selected based on weight assessment on each criterion by ANP.

Preference-Based Revenue Optimization for App-Based Lifestyle Membership Plans

The demand for a product is rooted in the consumers’ needs and preferences. Therefore, a pricing optimization model will be more valid if the demand function is represented under this basic notion. A preference-based revenue optimization model for an app-based lifestyle membership program is developed and solved in this research. The model considers competitor products and cannibalization effect from products in other fare-class, where both are incorporated using a preference-based demand function. The demand function was derived through a randomized first choice simulation that converts individual utility values into personal choices based on the random parameter logit model. Cannibalizing products are considered as competing products in the simulation scenario. In the pricing optimization, two and three fare classes based on the membership period are considered. The corresponding pricing optimization problem is a mixed-integer nonlinear programming problem with a solution-dependent objective function. Using enumeration, the three-fare-class optimal prices of Rp420,000, Rp300,000, and Rp60,000 for 12-month, 6-month, and 1-month membership, respectively, are better than those of the two-fare-class. Under this policy, the estimated total revenue is Rp30.56 billion, 41.74% greater than that of the current condition.

Quality Control on Minimizing Defect Product on 20 OE Yarn

Industrial businesses in Indonesia realize that consumer desires have changed over time. Consumers desire that becomes the main priority is quality. PT. Bitrate Industries, as a company that produces yarn in Semarang, always strives to improve product quality to the desires of consumers. The company faces quality control problems: the production process of 20 OE yarn, producing the highest defective products. The Six Sigma approach analyzes the causes of defects, identifies sources of variation, proposes improvements with 5W + 1H, and implements a quality control plan. Most defects occur in the production process in the autocross engine, which is caused by engine wear. Implementation of the kaizen approach can be given proposals in the form of improvements in maintenance, according to the existing scheduling and periodic replacement of parts. This study concludes that the proportion of defects is still in the controlled stage, but the quality control of the product is still needed. A quality improvement project with a Six Sigma approach can benefit any company that needs to find the most efficient way to improve product quality.
