“…Persediaan pengaman merupakan jumlah rata-rata persediaan yang disimpan yang dapat memenuhi ketidakpastian penawaran dan permintaan dalam jangka pendek (Silver, Pyke, & Peterson, 2016). Adanya persediaan pengaman memungkinkan perusahaan untuk mengatasi apabila perusahaan mengalami kehabisan persediaan (Shenoy & Rosas, 2018). Tingkat persediaan pengaman harus mencapai tingkat tertentu yang bisa digunakan selama proses pengiriman barang dan cukup untuk memenuhi permintaan, namun tidak menyebabkan biaya penyimpanan yang tinggi.…”

ABSTRACT This research was conducted with the aim of observing the production planning process applied by PT X then designing a comprehensive production planning and inventory control so that it can overcome the occurrence of shortages and excess of inventory in the company. The research was conducted by observing a springbed manufacturing company PT X in Makassar. The data used are primary and secondary data, using instruments such as interviews, conducted on staffs and management of PT X, site visits, as well as company historical data. The results of the research were in the form of production planning, through demand forecasting, master production schedule, and planning for resource requirements. In addition, the researcher also established an inventory control system that could support the company's production process using the EOQ method, safety stock, and reorder points. The results of the research are not necessarily applicable to other companies with different demand patterns or to companies with different industries. In addition, the methods used in production planning and inventory control are limited in this study. ABSTRAK Penelitian ini dilakukan dengan tujuan untuk mengamati proses perencanaan produksi yang diterapkan perusahaan manufaktur PT X, merancang perencanaan produksi dan pengendalian persediaan yang komprehensif sehingga dapat mengatasi terjadinya kekurangan maupun kelebihan persediaan pada perusahaan. Penelitian dilakukan dengan melakukan observasi pada perusahaan manufaktur PT X, perusahaan manufaktur yang memproduksi kasur per di kota Makassar. Data yang digunakan merupakan data primer dan sekunder, berupa wawancara yang dilakukan pada jajaran staf dan manajemen PT X, serta data historis perusahaan. Hasil penelitian berupa perencanaan produksi yang melewati tahap peramalan permintaan, pembentukan jadwal induk produksi, serta perencanaan kebutuhan sumber daya. Selain itu, peneliti juga membentuk sistem pengendalian persediaan yang dapat mendukung kelancaran proses produksi perusahaan dengan metode Economic Order Quantity (EOQ), persediaan pengaman, dan titik pemesanan kembali. Hasil penelitian belum tentu dapat diterapkan pada perusahaan lain dengan pola permintaan maupun pada perusahaan dengan industri yang berbeda. Selain itu, metode yang digunakan dalam pembentukan perencanaan produksi dan pengendalian persediaan pun menjadi keterbatasan dalam penelitian ini.

“…These systems have been studied for many years because they present computational complexities, even when two stages are assumed (Clark and Scarf, 1960; Simon, 1971). Two-echelon inventory systems can be continuous review (r,Q) or a periodic review (r,s,S), where r is the review frequency, Q is the order quantity, s is the reorder point and S is the order-up-to level (Shenoy and Rojas, 2018). Engelmeyer (2016) provided a systematic explanation of various inventory models, including some methods to manage intermittent random demand.…”

Repair part service level differentiation based on holding other parts shortage costs

PurposeThe article addresses the optimization of safety stock service levels for parts in a repair kit. The work was undertaken to assist a public transit entity that stores thousands of parts used to repair equipment acquired over many decades. Demand is intermittent, procurement lead times are long, and the total inventory investment is significant.Design/methodology/approachDemand exists for repair kits, and a repair cannot start until all required parts are available. The cost model includes holding cost to carry the part being modeled as well as shortage cost that consists of the holding cost to carry all other repair kit parts for the duration of the part’s lead time. The model combines deterministic and stochastic approaches by assuming a fixed ordering cycle with Poisson demand.FindingsThe results show that optimal service levels vary as a function of repair demand rate, part lead time, and cost of the part as a percentage of the total part cost for the repair kit. Optimal service levels are higher for inexpensive parts and lower for expensive parts, although the precise levels are impacted by repair demand and part lead time.Social implicationsThe proposed model can impact society by improving the operational performance and efficiency of public transit systems, by ensuring that home repair technicians will be prepared for repair tasks, and by reducing the environmental impact of electronic waste consistent with the right-to-repair movement.Originality/valueThe optimization model is unique because (1) it quantifies shortage cost as the cost of unnecessary holding other parts in the repair kit during the shortage time, and (2) it determines a unique service level for each part in a repair kit bases on its lead time, its unit cost, and the total cost of all parts in the repair kit. Results will be counter-intuitive for many inventory managers who would assume that more critical parts should have higher service levels.

“…Inventory is continually changing, and managing it necessitates a regular and meticulous examination of external and internal elements, as well as control through planning and review. Lead time, economies of scale, and uncertainties in the form of safety stock are the three main reasons for holding inventory (Samanta, 2015). The effectiveness of inventory management is affected by planning, storing records, employees skills and experiences, and funding (Chan et al, 2017).…”

This paper examines the automation of supply chain management through the implementation of Distribution Requirements Planning (DRP) automation project using Enterprise Resource Planning (ERP) system. A central question is addressed in this paper: from a resource-based view, what is the effect of the DRP automation through ERP system on the supply chain management in the Egyptian Fast-Moving Consumer Goods (FMCG) industry? Adopting a case study methodology in a leading Egypt-based manufacturer 'Juhayna Food Industries', this study is the first of its kind to provide a thorough analysis of the implementation of a DRP automation project using an ERP system and its effect on supply chain management, focusing on the informational flow of goods in the Egyptian FMCG industry. The study demonstrates that the automation of DRP using ERP systems has a positive and significant impact on supply chain functions including supply and demand planning, procurement, production, warehouses, and logistics in the Egyptian FMCG industry, improving data accuracy and efficiency. This research will help FMCG companies in their planning and distribution practices for the supply chain management of their products.
