Scheduling changes on the production floor are common in practice to meet the consumer demand and these cause the nervousness. The nervousness in turn will result in increased costs and reduced service level. This research deals with production batch size and buffer stock taking into account changes in a preliminary order. Change in the demand for a given day is announced one day before and this is viewed as it occurs randomly. This research was considered in two echelon supply chain system with a single supplier and single manufacturer. The development of model is transactional relationship and consignment stock contract relationship. This study also considers the backorder and production capacity according to the real condition. Numerical examples are given to demonstrate the performance of the models. From the numerical results, it appears that coefficient variation (CV) of the demand affects the results obtained using method of SM and LUC.

Applying Particle Swarm Optimization for Solving Team Orienteering Problem with Time Windows The Jin Ai; Evan Martinus Mahulae
Jurnal Teknik Industri: Jurnal Keilmuan dan Aplikasi Teknik Industri Vol. 16 No. 1 (2014): JUNE 2014
Publisher : Institute of Research and Community Outreach - Petra Christian University

The Team Orienteering Problem With Time Windows (TOPTW) is a transportation problem case that have a set of vertices with a score, service time, and the time windows, start and final at a depot location. A number of paths are constructed to maximize the total collected score by the vertices which is visited. Each vertice can be visited only once and the visit can only start during the time window of vertices. This paper proposes a Particle Swarm Optimization algorithm for solving the TOPTW, by defining a specific particle for representing the solution of TOPTW within the PSO algorithm and two alternatives, called PSO_TOPTW1 and PSO_TOPTW2, for translating the particle position to form the routes of the path. The performance of the proposed PSO algorithm is evaluated through some benchmark data problem available in the literature. The computational results show that the proposed PSO is able to produce sufficiently good TOPTW solutions that are comparable with corresponding solutions from other existing methods for solving the TOPTW.

Previous studies have been conducted to measure fatigue using flicker test. However, the validity of the device is still unknown empirically. This study proposed a modification of fatigue measuring apparatus based on flicker test. The modifications were developed from the framework of human factors product design, with the stages including analysis of the existing condition, operational concept, user requirements, performance criteria, system requirements, design prototyping, usability testing and final testing. The proposed apparatus consists of two main parts: a stimulus source and a control device as input. The stimulus is given by three lights with adjustable position and orientation angle. A LCD screen was provided to display status and result of the measurement. The control device consists of three buttons to respond the stimulus accordingly. Product testings were done through 1) a laboratory experiment with activities of critical reading and arithmetic complex and 2) a field study on a night bus driver. All the tasks selected represent works with a dominant mental workload. The laboratory experiments showed the range of Critical Flicker Fusion Frequency (CFFF) at work of 14-40 HZ, with the average decline of CFFF values of 5.3 Hz in arithmetic complex and 4.8 Hz in critical reading activities. The study on the night bus driver resulted in CFFF value range of 18-40 Hz with the average delta CFFF of 8.97 Hz. Both testings suggest that flicker test with CFFF indicators can be used to measure mental fatigue. In addition, the proposed framework used in this design development can be used as a reference in designing various products by taking human factor aspects as the focus such as user needs and user limitations.

Kontrol Optimal pada Model Economic Order Quantity (EOQ) dengan Inisiatif Tim Penjualan Abdul Latif Al Fauzi; Isnani Darti; Agus Suryanto
Jurnal Teknik Industri Vol. 19 No. 1 (2017): JUNE 2017
Publisher : Institute of Research and Community Outreach - Petra Christian University

Pengendalian tingkat persediaan stok suatu produk/barang merupakan salah satu kegiatan yang penting dalam kelancaran penjualan, yang juga berakibat pada keuntungan yang akan diperoleh dari penjualan suatu produk/barang. Model Economic Order Quantity (EOQ) merupakan salah satu model persediaan barang yang sering digunakan untuk pengendalian persedian barang. Pada artikel ini dibahas kontrol optimal pada model EOQ dengan inisiatif tim penjualan tidak hanya pada saat kondisi setimbang saja, tetapi kontrol optimal dengan usaha tim penjualan pada setiap saat. Strategi kontrol optimal dilakukan dengan meminimumkan biaya persediaan, biaya pembelian, biaya penjualan dan biaya usaha tim penjualan. Masalah kontrol optimal diselesaikan menggunakan prinsip maksimum Pontryagin. Solusi optimal yang diperoleh disimulasikan secara numerik menggunakan metode Sweep Maju-Mundur. Berdasarkan hasil simulasi numerik dapat diketahui bahwa semakin besar koefisien tingkat permintaan barang, maka proses persediaan barang akan lebih cepat berkurang. Selain itu semakin besar usaha tim penjualan, maka proses persediaan barang akan lebih sedikit bahkan lebih cepat habis.

Publisher : Institute of Research and Community Outreach - Petra Christian University

This paper discuses the concept of managing high-end, high-volume innovative products. High-end, high-volume consumer products are products that have considerable influence to the way of life. Characteristic of High-end, high-volume consumer products are (1) short cycle time, (2) quick obsolete time, and (3) rapid price erosion. Beside the disadvantages that they are high risk for manufacturers, if manufacturers are able to understand precisely the consumer needs then they have the potential benefit or success to be the market leader. High innovation implies to high utilization of the user, therefore these products can influence indirectly to the way of people life. The objective of managing them is to achieve sustainability of the products development and innovation. This paper observes the behavior of these products in companies operated in high-end, high-volume consumer product.
