Abstract:
Based on the data, there were still shortages of production from year to year and demand wereunstable in motorcycle chains manufacturer in Indonesia. To overcome these problems, the purpose of this research was to make production planning and inventory control consisting of forecasting, aggregate planning, Master Production Schedule (MPS), and Material RequirementsPlanning (MRP). Forecasting used the additive decomposition method (average of all data), multiplicative decomposition (centered on moving average), and winter method (additive and multiplicative). Aggregate planning used chase strategy, level strategy, and transportation model. Moreover, MRP used lot for lot, Economic Order Quantity (EOQ), and Periodic Order Quantity (POQ) methods. The test shows several results. First, the best forecasting is additive decomposition (average of all data) with MAD value of 3.033,57, MSE with 13.590.490,and MAPE with 10,083%. Second, the best aggregate planning is transportation model with the total cost of Rp7.708.398.390,00. Last, the best MRP method is the lot for lot with total cost Rp7.162.567.653,00.

Abstract:
The development of the human population in the world, especially Indonesia, to date is approximately 260 million people, making Indonesia in a big challenge where Indonesia must be able to meet the domestic drug supplies needed by the community. The availability of drugs is still an obstacle in the National Health Insurance in Indonesia, this requires the role of the pharmaceutical industry in supporting drug availability by implementing good supply chain management. The focus of this discussion is to look at drug supplies in Indonesia in meeting people's needs and identify factors for production planning, production capacity and raw material procurement for the pharmaceutical industry in supporting the availability of drugs to support the National Health Insurance. This research is a descriptive study by collecting information from various literatures on pharmacy and medicines in Indonesia with a focus on the discussion of production planning, production capacity and raw material procurement and delivery to pharmaceutical companies in supporting drug availability. Because the planning for drug needs used as a basis for drug procurement is inaccurate so that pharmaceutical companies cannot make accurate production plans and the quantity of drugs for the community is inaccurate, time and unavailable at any time, the need for and procurement of materials still depends on imported raw materials from abroad around 95% with a lead time of 1-3 months so that it has the potential to deplete drug supplies and make the National Health Insurance in Indonesia worse.

Abstract:
Mass customization (MC) is an advanced production mode in the 21st century that combines two opposite production patterns -- customization production and mass production. It keeps low production cost and fast delivery time, while meeting individual customers needs. Firstly, via analyzing the typical production management patterns (material requirement planning (MRP)/ just in time (JIT)), and based on the two strategies of modularization and postponement, the paper presented a push/pull manufacturing model to meet the demands of MC. This model integrates the two different production patterns (push and pull) to reduce inventory, production costs and production time. Before the customer order decoupling point (CODP), common components and selective components are produced via push of plan in presence of inventory. After the CODP, customization production is conducted by pull of orders.

Abstract:
This article finds the relationship of Inventory management with industries becoming sick. Inventory planning and control are of special importance to sales, production, and finance of any firm. Proper inventory management gives an idea of relationship between raw material, work-in-process and finished goods or consumption of finished goods. From the collected data it is clear that many local plants have either no fixed norm(s) or do not practice proper way of controlling the inventory. This might be the case in many third world countries. In this article it has been discussed how to overcome sickness of industries by controlling and standardizing inventory planning and control. Also how productivity and firm’s financial conditions are affected by proper inventory management has also been discussed in this article.

Abstract:
Purpose Significant transitions in firms (e.g. outsourcing) may impact the relative importance of production and inventory assets, affecting the hierarchical separation of planning decisions. The purpose of this paper is to contribute to planning literature by investigating how the production system and the planning environment influence the performance difference between hierarchical and monolithic planning. Further, it seeks to reduce the prevailing theory-practice gap in tactical planning. Design/methodology/approach Through an action research study, a monolithic model integrating tactical production planning decisions, subject to upstream supply chain constraints, with strategic investments decisions was developed, tested and implemented in a global OEM. Using the developed model and a measure of the capital cost of production assets relative to the cost of holding inventory, it is numerically examined how the production system and planning environment influence the performance of hierarchical and monolithic planning. Findings The research demonstrates the potential of integrating decisions and reveals significant performance differences between hierarchical and monolithic planning for firms with low capital cost relative to inventory holding cost. Research limitations/implications The findings suggest a fit between planning processes, the production system and planning environment. Future research should empirically validate the findings and propositions. Originality/value The paper combine capital investments and production planning decisions, which usually transpire at different hierarchical levels and on different time-horizons, and investigates the consequences of hierarchical separation through a real-life validated case and numerical analysis.

Abstract:
A key indicator of the efficiency of a production line is cyclic idle time. Manufacturers use heuristic line balancing techniques to determine the allocation of elemental tasks to workers so as to minimize labor costs. The productive, i.e. non-idle, portion of each cycle then reflects the efficiency of the line. Line balancing techniques determine the allocation of tasks based on a pre-specified throughput. When demand changes however, the line may have to be reconfigured to reflect the new desired flow rate, resulting possibly in a lower efficiency and a higher per-unit labor cost. This raises an interesting question: should one use a flow rate that corresponds to the higher efficiency, handling any mismatch with demand through the use of inventory or backordering, or should the aim be to match flow rate precisely with demand rate even though the resulting efficiency might be lower? This paper proposes an answer to this question by embedding line balance and efficiency into the framework of a well-known production planning model. A heuristic method for solving the extended model is developed, and its application demonstrated using numerical examples.

Abstract:
Demand forecasting is the basis of the inventory management. Aiming at the problem of subjective forecasting method, we use quadratic exponential smoothing method to establish the mathematical model, to forecast sales volume of product A in every month in 2013. And based on demand forecasting, we put forward ABC classification management method to solve the inventory management issues. The research result of this paper has important implications in improving the inventory management level for many enterprises.Demand Forecasting and Inventory ManagementInventory management is an important part of enterprise management, and it directly affects the business situation of enterprises. A reasonable inventory can significantly enhance the comprehensive competitiveness of enterprises; too much or too little inventory settings would have a bad impact on the business, and some company even bog down because of inventory problems companies bogged down because of inventory problems [1-2]. To do inventory management, what should we do in the first step. The answer is demand forecast. When business scale reaches a certain level, it would need strict, systematic demand forecasting. The more accurate the demand forecasting is, the more accurate inventory planning would be, and more favorable for business enterprises.Few companies are able to be completely in accordance with the order production, and the vast majority of businesses are not waiting for orders after arrival, then determine how much raw material and manpower needed, and how to arrange production. Because it often takes a long production cycle, and no one is willing to wait a month to buy a bag of washing powder. Successful companies always make accurate predictions for product demand, and then put into production according to forecasting [3]. Due to their more accurate predictions, they can often carry out a reasonable plan and inventory management. Inventory forecasting, its essence is demand forecasting [4]. Demand forecasting provides important information for inventory management such as inventory amount, lead time, inventory turns. Demand forecasting is based on research and statistics, to make a scientific and reasonable inference for product demand. Product demand generally is within a certain period, certain market range, the number of consumers’ demand for a product. Demand forecasting results can help companies determine the amount of raw material inventory and products, and provide enterprise continuous production of raw materials needed, save liquidity and reduce inventory costs, improving the comprehensive competitiveness of enterprises.Product Demand Forecasting Model

Abstract:
The responsible management of product return flows in production and inventory environments is a rapidly increasing requirement for companies. This can be attributed to economic, environmental and/or regulatory motivations. Mathematical modeling of such systems has assisted decision-making processes and provided a better understanding of the behavior of such production and inventory environments. This paper reviews the literature on the modeling of reverse logistics inventory systems based on the economic order/production quantity (EOQ/EPQ) and the joint economic lot size (JELS) settings to systematically analyze the mathematics involved in capturing the main characteristics of related processes. The literature is surveyed and classified according to the specific issues faced and modeling assumptions. Special attention is given to environmental issues. There are indications of the need for reverse logistics models' mathematics to follow current trends in ‘greening’ inventory and supply-chain models. The modeling of waste disposal, greenhouse-gas emissions, and energy consumption during production is considered as the most pressing priority for the future of reverse logistics models. An illustrative example for modeling reverse logistics inventory models with environmental implications is presented.

Objectives: The production-distribution inventory problem has two main sectors namely production and distribution. In this paper, the nonlinearmathematical model of extended star-ring supply chain network is developed.Methods: Planning a distribution network plays a vital role in minimizing the total expenditure of the project; to prove this, a ring network topology is taken to supply goods to the SWs and extended star network topology to supply goods to the selling stores. However, setting up separate SWs for each and every selling store will be highly expensive. Hence, keeping the minimum number of SWs is very important. Selection of SWs from the available SWs is done by replacing diverse values based on the distance limitation.Results: The suggested model is validated with the mathematical problem, and the optimum set of SWs is identified from the result. The result has been substantiated using analytic hierarchy process. Conclusion: The system of optimum number of SWs is obtained from the result.

Abstract:
Inventory management is one of the most important aspects in light steel construction business activities. The application of inventory management affects the continuity of the production process and improves the quality of service to consumers. Inventory is defined as an asset which includes goods owned by the company and has the potential to be sold within a certain business period in an effort to meet consumer needs at any time. Galvalume raw material inventory for the spandex roof production process often suffers from shortages due to immature planning. The shortage of inventory causes production not to run smoothly. The purpose of inventory management in this paper is to obtain an inventory policy to optimize the total inventory cost. The method used in this study is economic order quantity. Based on the results and discussion. Ordering raw materials will be made 6 times in a year with an order quantity of 116 with a safety stock of 12 units and will be ordered again when the raw materials are in 46 units. Total Inventory Cost (TIC) which was originally IDR 26.350.191,- can be saved to IDR 21.038.827,- so that the total savings that occurred amounted to IDR 5.311.364,- (20,15%).

Abstract:
This study proposes a methodology for the oil and gas businesses to keep their production plant productive with a minimum investment in carrying maintenance, repair, and operating inventory planning. The goal is to assist the exploration and production companies in minimizing the investment in keeping maintenance, repair, and operating (MRO) inventory for improving production plant uptime. The MRO inventory is the most expensive asset and it requires substantial investment. It helps in keeping the oil and gas production plant productive by performing planned and unplanned maintenance activities. A (Q, r) model with a stock-out and backorder cost approach is combined with a continuous inventory review policy for the analysis of class A items of oil and gas production plant MRO inventory. The class A items are identified through popular ABC analysis based on annual dollar volume. The demand for the inventory is modeled through Poisson distribution with consideration of constant lead time. The (Q, r) model in both stock-out cost and backorder cost approaches assigned higher order frequency and lower service level to low annual demand and highly expensive items. The stock-out cost approach shows an 8.88% increase in the average service level and a 56.9% decrease in the company average inventory investment. The backorder cost approach results in a 7.77% increase in average service level and a 57% decrease in average inventory investment in contrast to the company’s existing inventory management system. The results have a direct impact on increasing plant uptime and productivity and reducing company maintenance cost through properly managing maintenance stock. The analysis is carried out on the oil and gas production plant’s MRO inventory data, but it can be applied to other companies’ inventory data as well. All the results reflected in this research are based on the inventory ordering policy of two orders per year. The inventory ordering frequency per year may be other than two orders per year depending on the type of organization.

Abstract:
Globalization has had a significant impact on company’s management, particularly in the supply chain (lead time, investment in production capacity and technology, organization & management ...). The sales and operations planning (S&OP) include all the processes that link the strategic objectives of the enterprise with the production plan. The impact of the S&OP on operational performance was consistently and significantly demonstrated in the operational aspects of production ; quality (conformity of production, product quality and reliability), delivery (the delivery agility, reliability of supply, manufacturing deadlines, lead times), stocks (reduction of inventory levels, inventory optimization) and flexibility (flexible volume and mix). Our objective in this paper is to present, in the first part, a literature overview of the sales and operations planning, and various research and models developed. In the second part, we will emphasize the transversal aspect of our research that involves both operational issues, tactical and strategic in a context subject to different constraints.

Abstract:
This research aims to improve the operating delivery system of water-treatment chemicals by establishing a chemicals inventory policy for planning appropriate chemicals delivery to five customers in the case study. Currently the company does not exploit tradeoff between transportation cost and inventory holding cost which benefits for cost reduction in terms of inventory management and chemicals delivery. The customers demand for chemicals consumption is uncertain depending on the quality of raw water and production rate. While company has constraints such as limit of transportation truck quantity and inventory review interval by the company. Therefore, for the factors mentioned, this research uses the periodic review system which demand is uncertain as an inventory model. Data from customers chemicals consumption in 2012 is used to conduct the inventory order up to level (OUL) for planning chemicals delivery to customers. Then, the research tests the delivery plan by using Monte Carlo simulation compared to the actual operation data from January to June 2013. It is found that the proposed operating system can reduce inventory cost by up to 33%.

Abstract:
A production-distribution model has been developed that not only allocates the limited available resources and equipment to produce the products over the time periods, but also determines the economical distributors for dispatching the products to the distribution centers or retailers. The model minimizes production, inventory holding, backordering, and transportation cost while considering the time value of money. Since uncertainty is an inevitable issue of any real-world production system, then to provide a realistic model, the concept of fuzzy sets has been applied in the proposed mathematical modeling. To illustrate and show the feasibility and validity of the model, a real case analysis, which is pertaining to a mineral water bottling production factory, has been used. The case has been solved using a three-step solution approach developed in this study. The results show the feasibility and validity of the mathematical model, and also the solution procedure.

Abstract:
This paper studies a periodic-review production-inventory control model under an energy buy-back program over an infinite planning horizon, in which a fixed setup cost and compensation levels corresponding to various market states are involved. The objective is to identify the manufacturer’s optimal production-inventory policy that can minimize his total discounted cost or long-run average cost. By using Veinott’s conditions, it is shown that such a state dependent optimal policy is of either an [Formula: see text], or partly an [Formula: see text] type.

Abstract:
Environmental legislation and customer expectations increasingly force manufacturers to take recovery of used products into account in their production and inventory management. One of the areas concerned is production planning with returned products remanufacturing. In this paper, we discuss the optimal decision for a joint manufacturing and remanufacturing system in a multi-period horizon, including manufacturing decision, remanufacturing and disposal decisions of the returned product. Setup costs are considered for the manufacturing and disposal activities. For an n-period model, we derive an optimal solution structure for the three activities, where the solution parameters can be computed by dynamic programming approach.

Abstract:
This paper describes prototype management information systems used to support the transformation of a job-orientated manufacturer into a preferred supplier to the Aerospace Industry. As a jobbing manufacturer the company excelled at reactive management, responding rapidly to short lead-time demands. This approach, however, was inappropriate for the increasingly competitive production of steady state orders (‘runners’) and spare parts orders (‘repeaters’). As a result, the company experienced falling delivery performances and increasing work-in-progress, inventory levels and overtime requirements. Furthermore, there was only a modest understanding of customer requirements due to the poor visibility of the order book. There was also little awareness of internal and supplier capabilities, and the planning and control systems were non-existent, relying heavily on senior management expertise. The company, however, was reluctant to invest in new management information systems, aware of the risk of expensive systems unsuited to the company requirements. Instead, prototype solutions were developed using low-cost and readily available software, which provided the stability and visibility that the company required and formed the basis of a more long-term understanding of planning and control requirements. This paper describes the iterative prototype developments to support the new company infrastructure and quantifies the benefits that were achieved through their introduction.
