PT. XYZ is one of many paper manufacturing companies in East Java which produces Exercise Book. The company implements corrective engine maintenance system where new components replacement is done when the engine is damaged. This treatment system resulted in frequent engine sudden stopping. With so many breakdown frequencies resulting from the fact that the engine stops abruptly, the broken raw materials increases in number and causes losses for the company. To overcome that problem we need appropriate treatment strategies to minimize the frequency of breakdown. Another aim is to minimize downtime and maintenance costs incurred because of engine maintenance activity. There are 3 maintenance scenarios implemented to solve such problem, i.e. scenario based on the existing condition of the company, scenario of component replacement in accordance with Mean Time to Failure (MTTF) value, and scenario of component replacement when the reliability of the component has reached 70%. From those three scenarios we will manually carry out an interval maintenance planning and Monte Carlo simulation. The result of data processing shows that in order to minimize the number of Exercise Book engine breakdown we can apply the 3rd scenario namely the replacement of component when the reliability of component has reached 70%. To minimize the amount of downtime and maintenance costs appropriately we shall use scenario 2, namely the replacement of component based on the Mean Time To Failure (MTTF) value.

Abstract one of the national manufacturing industry company engaged in the manufacture of military products with the resulting product is plastic box 260. To minimize the waste that occurs lean manufacturing approach is assisted by one of the tools in the concept of lean value stream mapping (VSM) aims to describe the overall Information from the flow of raw materials to finished products. Waste identification begins with the waste relationship matrix (WRM) and waste assessment questionnaire (WAQ) to determine the percentage of waste with the 3rd largest rank. Further analysis is done by analytical hierarchy process (AHP) aims to know the criteria of weighting from waste that has the highest ranking. The recommendation of improvement based on the analysis of waste with the 3 largest (unccessary inventory, overproduction, motion) and takt time calculation is to apply 5S, to apply forecasting, to add a working facility in the form of cooling room, to do maintenance activities such as preventive maintenance, addition of tools and machine, Setting laser machine, and layout design of production floor layout.

Abstract Industrial processing of chicken/native is one of the many industry-based food productions. These industry players realize that to provide cheap products, quality, and fast is not enough to make improvements in the company's internal only. But also takes the role of all parties, from suppliers who provide raw materials, transportation companies that send raw materials from suppliers to the industry, as well as the distribution network delivering products into the hands of customers. Performance improvement requires the presence of Supply Chain performance measures beforehand. The results of these measurements will be used as reference for improvement of performance of the Supply Chain. The reason the use of AHP and MILP itself because of these two methods are expected to provide the best solution of existing problems, which AHP method can determine the weighting or desired supplier selection criteria from existing suppliers. While the MILP method alone is expected to maximize profits by considering the risks. The results of the application of the AHP method known value of most major sub-criteria weights that supplier B with value at a price of 0.594 sub-criteria, sub-criteria weights alternative on the quality of 0.493, the sub-criteria weights alternative delivery time of 0.387, an alternative to the sub-criteria weights accuracy number of 0493, and the weight alternative to the sub-supplier performance criteria for 0.374. While based on the application of linear programming methods of forecasting results are known supplier B has a stock of goods which are more stable than other suppliers to stock inventory in July amounted to 18.116 tails, august amounted to 18.524 tails, September amounted to 19.033 tails, October amounted to 19.542 tails, in month of november to 20.068 tails, december amounted to 20.559 tails, and in January next at 21.068 tails.

In a closed-loop supply chain area, the concept of sustainability is one of the primary factors that motivates companies to survive in a dynamic market. The purpose of this paper is to present a literature review of quantitative models in the remanufacturing process, especially mathematical models such as pricing decisions and cost models, reviewed from various scientific journals. Challenges to meet market demands, to boost efficient operational costs, and to increase profits have made researchers interested in deeply exploring this issue. Studies in the reverse supply chain area ensure that the supply process runs effectively and efficiently, meeting a level that is as good as when implementing the forward supply chain. Coordination and collaboration among companies, core acquisition strategy, model character behavior, and reverse channel structure are some characteristics of the quantitative models within the area of a closed-loop supply chain. Mapping was arranged to identify the involvement of research variables (core acquisition cost and remanufactured product price) and factors that were considered in the mathematical model of core acquisition (quantity and quality). Furthermore, the related literature on the issue was analyzed based on the involvement of the considered variables and factors. Finally, future research opportunities are presented as the result of the conducted literature review in this study.

The acquisition strategy of returned products has become essential in the study of reverse supply chain. There are three primary activities included in the process of a the reverse supply chain, the acquisition of returned products, the remanufacturing process, and redistribution. This literature review intends to study the existing relationship amongst supply chain players in a closed-loop supply chain (CLSC) model. In the remanufacturing process performed by the company, returned products must be collected from consumers. Therefore, remanufacturing companies rely upon consumers as cores suppliers. This makes the good relationship between the two become crucial in company operational sustainability successfully. In this study, the identified journal articles were categorized into types of structural relationships between supply chain players and network structures of a reverse supply chain. Types of structural relationships are ownership-based, service-contract, direct-order, deposit-based, credit-based, buy-back, and voluntary–based. There are four types of returned product collector and remanufacturer: Original Equipment Manufacturer (OEM), a third party (3PL), retailer, and remanufacturer. Discussion of the journal articles was presented in each category. After that, the structural relationship was explored to find its advantage and disadvantage, so that CLSC can be managed effectively and efficiently. As a summary, suggestions for future research were described as the result of the literature review conducted.
