Purpose The purpose of this study is to apply value stream mapping (VSM) in Malaysian pharmaceutical production warehouse. A current and future state value stream map from the raw material receiving end to the production unit was developed to find out waste and unwanted lead time. It was very much essential to cut down the supply chain lead time at the initial phase as the raw material unloading, sorting, temporary storage and dispatch to production were seen contributing to a huge lead time build-up. Design/methodology/approach The study was initiated with the selection of a product family, construction of the current state map, identification of various wastes and the development of future state map. Findings The expected outcomes of the study include the quantification of wastes, improvement in value-added percentage and lead time reduction. Research limitations/implications The study was carried out in a single pharmaceutical company. The results of the study are deployable and can be functional in similar production organizations. Contrary to common VSMs that capture core production processes, this study provides strong insights that shall help design lean supply chains, especially in the pharmaceutical domain. This paper has also addressed the viability of the lean in the pharmaceutical warehouse and the reduction in lead time to improve demand forecasting, marketing and sales. Practical implications The results of this study have indicated that a significant reduction in pharmaceutical warehouse supply chain lead time is possible as a result of the implementation of VSM from the supply chain’s perspective. Social implications The insights from this study help in understanding the pharmaceutical supply chain risks and their outcomes. Originality/value The paper reports a real-time study conducted in a warehouse of a pharmaceutical organization. Hence, the contributions are original.

Di dalam dunia persaingan global persaingan antar kompetitor semakin ketat sehingga dalam faktanya bisnis usaha yang dijalankan perlu terus untuk dikembangkan dan dilakukan perbaikan sehingga perusahaan mampu tumbuh dan bersaing. Sebuah perusahaan yang bergerak di bidang sertifikasi halal mempunyai beberapa kriteria usaha yang disertifikasi meliputi industri pengolahan, restaurant dan rumah potong hewan. Fokus utama objek yang diteliti adalah industri pengolahan. Berdasarkan data historis sertifikasi halal selama 2 periode mengalami kenaikan secara terus menerus sehingga proses pelayanan dan penanganan dalam sertifikasi halal menjadi bertumpuk dan menjadikan aliran informasi dan aliran dokumen pada supply chain menjadi panjang dikarenakan sistem baru yang digunakan merupakan sistem sertifikasi secara online yang belum lama di adopsi. Proses sertifikasi halal memakan waktu sehingga kualitas pelayanan pada aliran informasi dan dokumen tidak maksimal dan berbedabeda, aliran informasi dan aliran dokumen yang tidak efisien waktu yang pada akhirnya membuat lead time proses sertifikasi menjadi panjang dan tidak efektif. Analisis menggunakan value stream mapping (VSM). Hasil yang dicapai berupa (1)big picture mapping current state map dan future state map, (2) mengetahui value added dan non value added pada proses aliran supply chain sertifikasi halal, (3) membuat skala prioritas terhadap 7 waste untuk meminimalisir pemborosan diproses sertifikasi, kemudian jenis pemborosan yang paling sering terjadi pada jenis pembororsan waiting (28%) dan proporsi waktu aktifitas value added (VA) sebesar (54%) dengan non value added (NVA) sebesar (46%). Setelah perbaikan didapatkan hasil proporsi waktu aktivitas menjadi sebesar value added (88%) non value added (NVA) berkurang menjadi sebesar (12%) berdasarkan rancangan aktivitas yang telah di operasikan berkurang dari 30 aktivitas menjadi 28 aktivitas dengan perbaikan waktu proses mencapai 37 hari dari 50 hari.   In the world of global competition, competition among competitors is getting tougher, so in fact, businesses that are run need to be continuously developed and improved so that companies are able to grow and compete. A company engaged in halal certification has several business criteria that are certified covering the processing industry, restaurants and abattoirs. The main focus of the object under study is the processing industry. Based on the historical data of halal certification for 2 periods, it has been continuously increasing so that the service and handling process in halal certification has accumulated and makes the flow of information and document flow on the supply chain lengthy because the new system used is an online certification system that has not been recently adopted. . The halal certification process takes time so that the quality of service in the flow of information and documents is not optimal and varies, the information flow and document flow are not time efficient which ultimately makes the lead time of the certification process to be long and ineffective. Analysis using value stream mapping (VSM). The results achieved in the form of (1) big picture mapping of the current state map and future state map, (2) knowing the value added and non value added in the halal certification supply chain flow process, (3) making a priority scale of 7 waste to minimize the waste of certification processing , then the type of waste that most often occurs in the type of waiting (28%) and the proportion of time value added activities (VA) of (54%) with non value added (NVA) of (46%). After the improvement, the result shows that the proportion of activity time is equal to value added (88%). Non-value added (NVA) is reduced to equal to (12%) based on the activity design that has been operated. 50 days.

Purpose Lean implementation is vastly incorporated in core manufacturing processes; however, its applicability in the supply chain and service industry is still in its infancy. To acquire performance excellence and thrive in the global competitive market, many firms are adopting newer methodologies. But, there is a stringent need for production simulation systems to analyze supply chains both inbound and outbound. The era of face validation is slowly disappearing. Lean tools and procedures that provide future state assumptions need advanced tools and techniques to measure, quantify, analyze and validate them. The purpose of this study is to enable dynamic quantification and visualization of the future state of a warehouse supply chain value stream map using discrete event simulation (DES) technique. Design/methodology/approach This study aimed to apply an integrated approach of the value stream mapping (VSM) and DES in a Malaysian pharmaceutical production warehouse. The main focus is diverted towards reducing the warehouse supply chain lead time by initially constructing a supply chain value stream map (both present state and future state) and integrating its data in a DES modelling and simulation software to dynamically visualize the changes in future state value stream map. Findings The DES simulation was able to mimic the future state lead time reductions successfully, which assists in better decision-making. Improvements were seen related to total lead time, process time, value and non-value-added percentage. Warehouse performance metrics such as receiving, put away and storage rates were substantially improved along with pallet processing time, worker and forklift throughput usage percentage. Detailed findings are clearly stated at the end of this paper. Research limitations/implications This study is limited to the warehouse environment and further additional process models and functional upgrades in the DES software systems are very much needed to directly visualize and quantify all the possible Lean assumptions such as radio frequency image identification/Andon (Jidoka), 5S, Kanban, Just-In-Time and Heijunka. However, DES has a leading edge in extracting dynamic characteristics out of a static VSM timeline and capture details on discrete events precisely by picturizing facility modification and lead time related to it. Practical implications This paper includes all the fundamental pharmaceutical warehouse supply chain processes and the simulations of the future state VSM in a real-life context by successfully reducing supply chain lead time and allowing managers in inculcating near-optimal decision-making, controlling and coordinating warehouse supply chain activities as a whole. Social implications This integrated approach of DES and VSM can involve managers and top management to support the adoption of anticipated changes. This study also has the potential to engage practitioners, researchers and decision-makers in the warehouse industry. Originality/value This study involves a powerful DES software package that can mimic the real situation as a virtual simulation and all the data and model building are based on a real warehouse scenario in the pharmaceutical industry.

Fierce competition encourages companies to make continuous improvements to achieve better working efficiency. One method to improve the working efficiency is using the concept of lean manufacturing. The efficiency of the existing work in PT. Rimba Kencana is still not good because there are many processes that are not uniform and because of that, production lead time is increased. By using value stream mapping and value stream analysis tools (VALSAT), the production processes in the company are mapped into the current state mapping and future state mapping. In the current state mapping, the total value of production lead time is 59.49 days and the value of process cycle efficiency (PCE) is 0.013%. After doing improvement on welding department, the total value of production lead time decreased to 48.22 days and the value of process cycle efficiency becomes 0.016%. Keywords: Efficiency, Value Stream Mapping, Value Stream Analysis Tools
