Supply Chain Process

In recent years, the e-commerce market has grown significantly, and the online retail market has become very competitive. Online retailers strive to improve their supply chain operations to reduce costs and to improve customer satisfaction. Value stream mapping (VSM), a tool created by the lean production movement to identify and reduce errors, losses, and lead time and to improve value-added activities, has been proven to be effective in many manufacturing processes. In this study, we investigate the application of value stream mapping (VSM) in the supply chain of an e-commerce retailer on Amazon. By visualizing the entire supply chain with VSM, the waste that is produced during the delivery process from the retailer to the customer was identified. The five whys method was then applied to find the root cause of the waste. Furthermore, a scoring method was developed to evaluate and compare two different supply chain logistic models to identify a strategy for improvement. This study provides a systematic methodology to understand, evaluate, and improve the entire e-commerce supply chain process utilizing VSM. It was demonstrated that the methodology could improve supply chain management efficiency, customer satisfaction, and cost reduction.

Value Stream

Lean Manufacturing is a powerful philosophy, which advocates minimization of waste throughout the value stream both within the organization and enterprise which includes the supply chain. A concept, which was first used by automobile manufacturers to enhance their operational efficiencies, Lean focuses on driving out non-value added activities from a company’s operation, while streamlining its value added activities. A number of companies in the United States have adopted the Lean Manufacturing philosophy to reduce cost and increase efficiency. To augment the existing training programs five new simulation tools in Ship Design Processes, Supply Chain Integration, Ship Repair Processes, Value Stream Mapping and Scheduling were developed under a grant from National Shipbuilding Research Program (NSRP) by Old Dominion University, Northrop Grumman Newport News and South Tidewater Association of Ship Repairers. The paper will discuss the design, development and implementation of two of these new simulation tools.

Value Stream

Application of a lean concept to supply chain management for the block rubber industry is presented. It seeks to reduce the total systemwide cost by reducing wastes throughout the supply chain. Value stream mapping is used to identify non value added activities in the chain. Four major stakeholders are included: rubber grower, minor collector, major collector, and manufacturer. Four study steps are involved: 1) collection of data for a supply chain model constructed; 2) creation of a value stream map and identification of non value added activities; 3) analysis of root causes of non value added activities, or wastes, identified in the first two steps; and 4) proposal of practical guidelines to reduce or eliminate the wastes. Results show that transportation contributes the second highest cost after personnel cost, but is more practical to be trimmed. Hub-spoke concept along with vehicle routing analysis is recommended to be further explored in depth for practical implementation.

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.

Nowadays automobile industry, as manufacturers structure and construct vehicles all-inclusive, their supply chains become progressively perplexing with difficulties in the method of profitability and investor worth value such as excess inventory over the production network and absence of permeability of providers. So as to expand the aggressiveness of the automotive industry with store network, here lean administration idea is incorporated as lean supply chain management (LSCM).The Lean supply chain is utilized to streamline the business forms by wiping out waste and non-value added activities. The association between lean and SCM is one of the techniques for expense and time decrease to improve the viability. The lean supply chain is likewise centered around advancing the procedure of all production network and scanning for rearrangements. This research paper is proposed a lean supply chain managementvalue stream mapping (LSCM-VSM) is utilized to dispense with waste and improved operational methodology and efficiency. It is a procedure of envisioning mapping stream of information and producing the future-state map with better strategies and execution. The exploratory outcomes demonstrate the production lead time (PLT) by executing the proposed LVSM and future more assesses the total cycle time (TCT) and value-added ratio(VA%) of a value stream.

PurposeProcess models specific to the supply chain domain are an important tool for the analysis of interorganizational interfaces and requirements of information technology (IT) systems supporting supply chain decision-making. The purpose of this study is to examine the effectiveness of supply chain process models for novice analysts in conveying domain semantics compared to alternative textual representations.Design/methodology/approachA laboratory experiment with graduate students as proxies for novice analysts was conducted. Participants were randomly assigned to either the diagram group, which worked with “thread diagrams” created from the modeling grammar “Supply Chain Operation Reference (SCOR) model”, or the text group, which worked with semantically equivalent textual representations. Domain understanding was measured using cognitively demanding information acquisition for two different domains.FindingsDiagram users were more accurate in identifying product-related information and organizing this information in a graph compared to those using the textual representation. The authors found considerable improvements in domain understanding, and using the diagrams was perceived as easy as using the texts.Originality/valueThe study's findings are unique in providing empirical evidence for supply chain process models being an effective representation for novice analysts. Such evidence is lacking in prior research because of the evaluation methods used, which are limited to scenario, case study and informed argument. This study adds the diagram user's perspective to that literature and provides a rigorous empirical evaluation by contrasting diagrammatic and textual representations.
