Optimalisasi Infrastruktur Jaringan dengan Teknologi Fiber Optic di PT. Sinar Nusantara Industries

PT. Sinar Nusantara Industries is a manufacturing company that produces famous building materials. One of the important divisions in the company's operations is the Information Technology (IT) division that is responsible for network infrastructure. Currently, the company uses UTP cables for the network, but the distant inter-building distance leads to connectivity instability. To address this problem, the study proposes replacing the UTP cable with fiber optics from the server room to the finished product warehouse (GPJ) to improve the network infrastructure at PT. Sinar Nusantara Industries. This research uses the PPDIOO method (Prepare, Plan, Design, Implement, Operate, Optimize) to ensure each step is done in a structured manner. Research results show that the use of fiber optic cables increases network speeds from 100 Mbps to 300-500 Mbps and improves the stability and reliability of remote connections. The implementation also utilizes fast connectors to facilitate connectivity without splicing, making it more effective. Thus, this move is expected to improve network performance and security in PT. Sinar Nusantara Industries

Research on finished product warehouse inventory based on spatial segmentation

This paper proposes a finished product elevated warehouse inventory based on space segmentation, which does not need to control the low storage capacity in advance, nor does it need to stop the inventory, and can use the stacker to carry out the handling task when it is idle. Taking the finished product elevated warehouse of 8 roadways and 9 floors as an example, the inventory work of two floors can be completed every working day, and the inventory work of the whole reservoir area can be completed in 4.5 working days. The first step is to complete the division of the roadway by layer, and then move the finished product pallets of the layer requiring inventory to other layers. After WMS completes the clearance and transportation of all finished product pallets of this layer, the warehouse management personnel will enter the warehouse to manually verify the retention of finished product pallets. This step can ensure that there are finished product pallets in the cargo location with information. Then cooperate with the comparison of finished product pallets in the delivery area of finished product warehouse to realize this step, which can ensure the consistency between information and physical objects. The results show that this inventory method can completely replace the existing complicated manual inventory business, effectively realize the inventory work of finished product elevated warehouse, and provide an accurate and efficient inventory scheme for similar logistics elevated warehouse.

Optimization of the Structural Design of the Process of Fertilizer Mixing and Biomodification of Solid Mineral Fertilizers

A rational structural construction of the general process of fertilizer mixing and biomodification of solid mineral fertilizers is proposed. It covers all the process steps starting from the receipt of individual mixing components at the enterprise fertilizer mixing section through to the shipment of the finished biomodified fertilizer mixture to the finished product warehouse. The condition of synchronous operation of units and assemblies of a fertilizer mixing line is substantiated, where its maximum productivity, high mixing intensity and good quality of the mixture are achieved.

Modeling the Multi-channel Section in the Supply Chain System using the Multiserver Queue Analogy

The industry generally consists of a supply chain system. The main constituents of any supply chain system are suppliers, manufacturers, distribution centers, and retailers. The system configuration can be straight chain, branched, cyclic, or a combination of all. An analytical model is needed to study system behavior as a result of the dynamics of its constituents. Modeling a multi-channel section becomes quite a challenging job in this regard. A method of modeling the multi-channel section will be discussed in this paper by adopting multi-server queues. As is well known, in a multi-server queue, there is a branching point at which the flow of entities begins to spread across several parallel servers. In the modeling perspective of this paper, the branching point is in the buffer (finished good warehouse in the factory, i.e., the focal echelon). That is the end of the waiting line from which the entity specifically moves to one of the servers, or in this context; it is called a channel. In this paper, the number of channels can be any, generalizable, can be more than two. Hence, the subsystem studied includes a factory, finished product warehouse, and several distribution centers. The factory produces by the mechanism of, where and r are stopping point and production restarting point, respectively. Production stops when the quantity of finished product in the warehouse reaches units and will restart the production when the quantity drops to the same or lower than units. The model is developed under Markovian assumptions by considering the quantities of production rates, the number of distribution centers (channels), travel time from factories to each distribution center, delivery lot size, and the time between the arrival of orders from distribution centers. The system under study is seen as a case of two echelons, namely factories and distribution channels. The numerical model obtained is applied to one case example with certain conditions. Comparisons with discrete simulation results give relatively small and acceptable differences. So, in the future, this model can complement the overall modeling of the supply chain system, a multi-echelon system with multi-channel distribution.

Simulation-Based Decision Support System to Improve Material Flow of a Textile Company

To remain competitive, companies must continuously improve the processes at hand, be they administrative, production, or logistics. The objective of the study described in this paper was to develop a decision-making tool based on a simulation model to support the production of knits and damask fabrics. The tool was used to test different control strategies for material flow, from the raw material warehouse to the finished product warehouse, and thus can also be used to evaluate the impacts of these strategies on the productivity. The data upon which the decision support tool was built were collected from five sectors of the plant: the raw material warehouse, knit production, damask production, finishing work, and the finished product warehouse. The decision support tool met the objectives of the project, with all five strategies developed showing positive results. Knit and damask production rates increased by up to 8% and 44%, respectively, and a reduction of 75% was observed in the waiting time on the point of entry to the finishing work area, compared to the company’s existing system.

Analisis Penyebab Cacat Produk Santan Kemasan dalam Penetapan Critical Control Point dengan Pendekatan HACCP di PT. X

Hazard Analysis Critical Control Point (HACCP) ia a quality control system from the preparation of raw maerials to the product and accepted by consumers. HACCP is a requirement for guaranteeing the safety of food products produced according to company quality standards.PT. X produces packaged coconut milk as one of the main products and has implemented HACCP in every production process of its products. The packaged coconut milk that is produced often gets bloated in the finished product warehouse before the product is distributed. Therefore it is necessary to analyze the application of HACCP in the production of packaged coconut milk. HACCP application in the packaged coconut milk production process has set 4 Critical control points. CCP 1 (UHT Sterilization System & Aseptic Tank), CCP 2 (Filtration 500 micron), CCP 3 (Product Sterilization at 140-148ºC) and CCP 4 (Filling with Astepo Filler Filling Machine). Each Critical Control Point has physical and biological hazards, which must be controlled to ensure food safety. The research objective was to analyze the implementation of HACCP plan for coconut milk products based on SNI No. 01-4852-1998 regarding the HACCP system and analyzing the causes of product defects (bloating) in the determination of the CCP. Based on the analysis of HACCP application and the causes of product defects in packaged coconut milk, product defects due to bloating are not defects in the production process but defects caused by cross-contamination of microbes after filling. Cross contamination occurs due to cracks in the neck of the aseptic bag cup that cannot be detected directly, and the use of tools that should not be used during the filling process.

Design of logistics information system in the finished product warehouse with the waterfall method: review literature

The process of sending and loading finished goods is very important. According to some experts, transportation activities spend 44% of the total cost. Even in Indonesia transportation costs can reach more than 60%. In practice, one way of saving on transportation costs can be done by minimizing the waiting time for loading finished products in the warehouse. The slow delivery of information from the logistics department to the warehouse can cause high load times for finished products. This can lead to delays in product delivery to consumers. The method used in this paper is the Waterfall method. The Waterfall method provides a software flow approach in sequence or sequentially starting from analysis, design, implementation, verification, and maintenance phase.

Finished Product Warehouse Layout Design Using Shared Storage Method

PT. XYZ is a private company engaged in the business of producing ceramics. The problem in the current warehouse is the presence of defective ceramic products due to irregular placement of finished products. Irregular placement of ceramic products, which can cause inefficiency in picking time and make it difficult for workers because of the limited space for movement that can hinder the movement of workers on the production floor. The above problems can be overcome by using the Shared storage method where goods are placed in the storage area closest to the entrance-exit (I/O) door. This method would be better used in types of factories that have the same product dimensions or not much different. The lack of good procedures for arranging goods in the warehouse causes problems in the warehouse, so that the warehouse seems cramped and less organized. The condition of the warehouse layout that is not based on a comprehensive layout design can lead to inefficiency in the time of taking and storing materials and making it difficult for operators to handle materials due to warehouse limitations. In this case, the process of placing goods in the warehouse at the ceramic factory of PT. XYZ will be arranged to reduce the forklift movement distance shorter which can be seen from the results of the proposed design on the layout of the finished product placement in the warehouse. Looking at the design of the proposed ceramic product warehouse layout, the percentage of total travel distance savings in the finished product warehouse is 37.76%.

The main stages of production include intake, unloading and refining of raw materials; grinding grain components in the same fraction; extruding and cooling grain components; grinding extruded grain components; weighting of feed components; mixing the components to a homogeneous mixture; conditioning; expansion of bulk feed; drying; size control of finished products; spraying on the surface of the liquid components; cooling; feed packaging

INCREASING OPERATION EFFECTIVITY OF METAL PRODUCTS LOADING POINTS BY THE RATIONAL USE OF BRIDGE CRANES

Purpose. Taking into account research and improvement of transport and storage processes for loading railway cars with bridge cranes the purpose of the study is the analysis of actual crane operation zones, development of simulation models of their functioning and determination of the most effective load technology. The real object of the study — the finished goods warehouse of a metallurgical enterprise — is formalized as a linear load point. Methodology. To analyse various options for the crane operation zones of the investigated object, the simulation modelling method was used. It was taken into account that each bridge crane can load railway cars, which are located in different zones of the loading track. Situations when the cranes are on the same crane ways during cargo operations and the service area of cars partially coincides were considered. Under such conditions, cranes can interfere with each other; it makes it difficult to carry out the transport-technological process of loading. Findings. A simulation model in which the service elements, which are the individual cargo packages, move along certain routes has been developed. Freight traffic volumes are set according to certain laws of random value distribution, taking into account the stochastic nature of real transport processes. A model of the linear loading point of railway cars with bridge cranes has been developed. It allows us to analyse the performance indicators of various options for assigning service areas to loading facilities. The analysis of such indicators as an average transporting time of service elements, a time percentage of cranes work and idle, time for separate movement operations of freight traffic volume is performed. Based on the developed model, a procedure has been developed to determine the most effective strategy for managing the loading point operation. The methodology, which has been tested on the example of a finished product warehouse of a metallurgical enterprise, and allows reducing the total costs in the process of rolled metal products loading has been developed. Originality. Theoretical research and improvement of the operation models of the metallurgical enterprise`s transport and storage complex due to the rational assignment of vehicle loading areas to the cranes. Practical value. The results obtained make it possible to increase the efficiency of the transport and storage complex by reducing the time spent by railway cars in the system with the rational use of loading resources.

Location Management of Cloud Forklifts in Finished Product Warehouse

The order picking process has been considered as the most time-consuming and costly activity in warehouse management. Efficient location management, including product location management and storage location assignment management, serves as the key to reducing product searching time and traveling time during the process. This research is motivated by a real-life industrial case, which is from a forklift manufacturer that encountered the underperformance in warehouse management. Excessive time was consumed in searching and picking the forklift in finished product warehouse, which thus led to great waste in resources and even the postponement of delivery. To solve this problem, this paper first presents the details about the problem and related processes. A conceptual model of cloud forklifts and its life cycle oriented management platform is then proposed. Accordingly, a prototype system named cloud forklift warehouse management system (CFWMS) is built based on the proposed model. The suggested model and system architecture is designed and developed with the commonality for general warehousing processes, and therefore can be easily configured and applied to any general warehouse environment. Results and details of implementation for the real-life case are also provided to demonstrate the validity of the proposed model and CFWMS.

A Continuous Genetic Algorithm for Pickup and Delivery Problem in a VRP environment.

Picking and delivery problems and its combinations are considered as NP-hard problems according to the computational complexity. For those problems, exact algorithms cannot propose appropriate solutions needing scenarios such as large industrial manufacturing enterprises or commercials, asset custody and logistics operators. These companies need to manage their inventories and movements across their stores through approximated algorithms with the objective of minimizing both cost of inventory and manpower for delivery. Picking and delivery problem as an extension of VRP family required metaheuristics solutions. Present paper discusses an application of continuous genetic algorithm for solve a case where the stores have lots of products and where there is a steady flow of movements to locate and dispatch them. Finally, we consider the problem of constrained optimization. It illustrates an example in which an algorithm is used crowded with penalty. The results indicate that the conventional genetic operators (crossover and mutation) lose effectiveness when the overall solution is in the border of the feasible solution space. For this reason, we propose a new genetic operator for best results. The test instance has been extracted from a Peruvian plant produces and commercializes ceramic (bathrooms, tiles, pipes, etc.) This enterprise has 550 different products in its catalog, has five finished product warehouse of 1500 and making distributions to three countries and over 15,000 points of sale.

Model and analysis of integrated production–inventory system: The case of steel production

The study originated from an industrial case study in the field of steel production, but it presents a larger interest, as many other manufacturing fields have similar concerns (e.g. foundries, food, textile and paper industries). A significant phase of steel manufacturing is the product cooling (likewise, drying in paper and textile production, or maturing in food production). This phase may be completed in different ways, but (1) it must be carried out in the finished product warehouse and (2) it must meet both production optimisation and customer needs. The latter requirement acquires a strategic relevance in JIT environments. The present study proposes a mathematical model to find the optimal production schedule of steel billets, based on the relevant parameters of the productive system (set-up and processing times, demand profile). In the industrial case examined, the negative impact of holding costs on cash flows is also linked to the space required by the cooling process, which depends on the production schedule adopted. In other words, the finished product storage can be considered a part of the manufacturing cycle and impacts on it. In the case of steel plants operating in JIT environments, the warehouse must be promptly emptied and carefully managed to exploit the available space. Thus, the effect of inventory costs is examined in a production–inventory system with finite capacity, where products are made to order and share the same manufacturing facility. The study is completed by an experimental analysis to investigate the effect of variations in the relevant parameters of the problem.

Pull-type manufacturing systems with multiple product types

A multiple-product facility consisting of a manufacturing process and a finished product warehouse for several types of products is considered. An (R, r) continuous-review inventory control policy is applied to each type of product in the warehouse. The demand arrival process of each type is assumed to be Poisson. The processing times and the set-up times are arbitrarily distributed. We have developed an iterative procedure to approximately compute the average inventory level of each product in the warehouse under different priority schemes

Multi-stage, pull-type production/inventory systems

A production/inventory system consisting of multiple stages in series with arbitrary processing times and with intermediate buffer inventories is considered. There is a finished product warehouse at which demand occurs for the finished products according to a compound Poisson process. Inventory levels of both intermediate and finished stocks are controlled by a continuous-review (R, r) inventory control policy. Production at a stage continues until the inventory level in the downstream buffer reaches its target value R. Once the inventory level drops to its reorder level r, the stage undergoes a set-up and production resumes. An approximation method is developed to obtain the steady-state performance measures of the system. Numerical examples are presented to show the accuracy of the proposed method.

Look-back policies for two-stage, pull-type production/inventory systems

The authors consider a two-stage, pull-type production/inventory system with a known service mechanism at the first stage. Set-ups and start-ups are involved in the operation of the second stage. It is assumed that the first stage has always raw material to process. Between the two stages, there is an intermediate storage of work-in-process inventory that operates with the base-stock policy. Under this policy, the first stage produces as long as the intermediate buffer is not full. The second stage produces to store in the finished-product warehouse and operates with the continuous-review (R,r) policy. This policy implies that if the inventory is below or equal to the reorder level r, then a request for production is placed at stage 2. The production continues until the warehouse inventory reaches the capacity limit R. A semi-Markov decision model is used to obtain an optimal policy for the operation of the second stage. The structure of the optimal policy suggests use of a suboptimal look-back policy that delays the set-up at the second stage if the buffer lacks sufficient material. >
