Supply units in each command are multi-tiered and each supply unit keeps a supply level independently, which can cause excess stock, leading false reports to the Logistics Command and increasing difficulties in managing user needs. This causes excess assets and the excess then causes deformation in demand. therefore, the supply support systems of our armed forces have become high-cost/low-efficiency and are insufficient to meet the needs of users in combat units. Civilian corporations and the US Department of Defense are downsizing the aforementioned multi-tiered supply systems thus revolutionizing efficient and effective logistics by adopting Supply Chain Management(SCM), and Prime Vendor policies. Prime Vendor policy is a logistics support method that allows users to directly request and receive supply items from suppliers, based on supply contracts between suppliers and central maintenance organizations like KDA. In other words, it is a system that allows for users to make orders to suppliers directly and suppliers to deliver goods to the users directly, cutting out the middle stage, thus allowing an efficient supply. This is a way forward in finance that cuts costs in net supplies and allows an efficient utilization of civilian assets. which is also known to fasten the speed of logistical support and stripping down the logistical structure. therefore, this report will explore Prime Vendor policies adopted in certain number of units for medical supplies that were taken in consideration of improvements in stock management in civilian organizations and the US Army, and aims to apply such policies for repair parts.

Now that we're in the big data era, data has taken on a new significance as the storage capacity has exploded from trillion bytes to petabytes at breakneck pace. As the use of cloud computing expands and becomes more commonly accepted, several businesses and institutions are opting to store their requests and data there. Cloud storage's concept of a nearly infinite storage resource pool makes data storage and access scalable and readily available. The majority of them, on the other hand, favour a single cloud because of the simplicity and inexpensive storage costs it offers in the near run. Cloud-based data storage, on the other hand, has concerns such as vendor lock-in, privacy leakage and unavailability. With geographically dispersed cloud storage providers, multicloud storage can alleviate these dangers. One of the key challenges in this storage system is to arrange user data in a cost-effective and high-availability manner. A multicloud storage architecture is given in this study. Next, a multi-objective optimization problem is defined to minimise total costs and maximise data availability at the same time, which can be solved using a technique based on the non-dominated sorting genetic algorithm II (NSGA-II) and obtain a set of non-dominated solutions known as the Pareto-optimal set.. When consumers can't pick from the Pareto-optimal set directly, a method based on Principal Component Analysis (PCA) is presented to find the best answer. To sum it all up, thorough tests based on a variety of real-world cloud storage scenarios have proven that the proposed method performs as expected.

Intelligent Character Recognition System for Account Payable (ICRS AP) Automation represents the process of capturing text from scanned invoices and extracting the key fields from invoices and storing the captured fields into properly structured document format. ICRS plays a very critical role in invoice data streamlining, we are interested in data like Vendor Name, Purchase Order Number, Due Date, Total Amount, Payee Name, etc. As companies attempt to cut costs and upgrade their processes, accounts payable (A/P) is an example of a paper-intensive procedure. Invoice processing is a possible candidate for digitization. Most of the companies dealing with an enormous number of invoices, these manual invoice matching procedures start to show their limitations. Receiving a paper invoice and matching it to a purchase order (PO) and general ledger (GL) code can be difficult for businesses. Lack of automation leads to more serious company issues such as accruals for financial close, excessive labor costs, and a lack of insight into corporate expenditures. The proposed system offers tighter control on their invoice processing to make a better and more appropriate decision. AP automation solutions provide tighter controls, quicker clearances, smart payments, and real-time access to transactional data, allowing financial managers to make better and wiser decisions for the bottom line of their organizations. An Intelligent Character Recognition System for AP Automation is a process of extricating fields like Vendor Name, Purchase Order Number, Due Date, Total Amount, Payee Name, etc. based on their x-axis and y-axis position coordinates.

Developers have, for some time now, recognised the benefits of acquiring "brownfields" sites for future urban development. The term “brownfield” generally refers to sites that have been previously occupied and in most cases this occupation has been for industrial usage. A key issue that developers face when considering the acquisition of a former industrial site is contamination and the costs associated with remediating the land to a level that renders the site suitable for its proposed use. Understanding all of the issues and implications associated with the remediation of contaminated land can be quite daunting. The process of remediation brings together a number of stakeholders that all have some influence on the outcome of the works. The stakeholders include the vendor, the purchaser, the regulatory authorities i.e. EPA and council, the Site Auditor and local residents. Careful planning and negotiation with the above stakeholders should be considered before committing to any remediation project.n project.

Authority control enables us to retrieve information accurately by coordination and cross reference of headings. It is considered that authority control is needed in machine readable catalogs as well as in conventional catalogs. Taylor, Maxwell and Frost divided automated authority control systems into major vendor and network systems then available into two groups. The first group was defined as a system that processes a library's machine readable catalogs on the tape against an automated authority file. The second group offers an online access to catalogs and authority records. This group was further subdivided into linked or integrated systems and unlinked systems. If authority work is shared with many libraries the costs can be considerably reduced and the quality of catalog data base can be controled by standardization of headings used in participating libraries. The NACO is a project for sharing of authority records started in 1977 by L.C. And LSP furthers the ability to share authority records. A project as the NACO is necessary not only in America but also in the other countries The responsible organizations for national bibliographies of the countries must take much interest in these matters.

Recently, Vendor Managed Inventory(VMI) is commonly recognized as one of the supply chain application that delivers clear value to the sectors of electic& electronic Components. VMI is a process in which a supplier generates orders for its distributor based on demand information sent by the distributor. VMI is providing the benefits of smoother demand, lower inventories and reduced costs. This case study focused on Improvement of Inventory Efficiency by VMI. The results indicated that VMI allowed the company to serve its customers more surely and efficiently.

The steel bars account for a high percentage of material costs for the current construction projects. At the present time, most of the construction projects for the factories of thin-film transistor liquid crystal display (TFT-LCD) complete the transactions of steel bars when the suppliers ship the steel bars to the temporary storage/processing sites. This paper applies the buy-in concept in the Theory of Constraint (TOC) on the supply chain of steel bars. In this study, suppliers are required to establish warehouses at the construction sites and complete the transactions when the formed and processed steel bars are shipped into the factory sites. The aim is to find a win-win solution to meet with the expectations from constructors as they hope that there is no need to build up inventories but supply is ready at any time. Also, this paper compares and analyzes the traditional supply/inventory model of steel bars and the Demand-Pull (D-P) model under the TOC framework. It is proved that Vendor Management Inventory (VMI) in the D-P model is able to more effectively manage steel bars as a material.

Past studies in e-commerce loyalty were mostly focused on the effects of customer satisfaction and trust on loyalty toward online vendors. Few studies investigated the impacts of switching barriers, whilst they are widely proven to affect customer loyalty in offline commerce. Even in a handful of studies that did deal with switching barriers, their treatment of the subject remained at best superficial. This may have to do with the fact that switching costs in e-commerce could be comparatively negligible, as switching to another online vendor often involves one simple mouse click. In this study, we investigated the impact of switching barriers on loyalty under the e-commerce context. Furthermore, the extent of switching barriers which could be affected by those positive factors (most constructs were adopted from IDT) was also examined. The statistical testing results revealed that combined model which includes both the positive factors and the switching barriers explains the loyalty formation process more strongly ($R^2$ = 0.543) than each separated models ($R^2$ = 0.468 for positive factor only model, and $R^2$ = 0.365 for switching barrier only model). While only the two switching barriers such as convenience and emotional were shown to be statistically significant, we found that trust strongly influences customer's emotional barrier, let alone direct impact on loyalty, which thereby influences loyalty. The results offer insights for better understanding switching barriers in e-commerce related applications.

Purpose: This study intends to examine how VMI with consignment performs over time and find out its on-going impacts on the individual supply chain member's achievement. Research design, data, and methodology: This study formulates the mathematical model that represents two-stage supply chain system. By analyzing the numerical examples, this study compares VMI with consignment with the traditional system. Results: VMI with consignment eventually makes higher supply chain profit than the traditional system, even though it's early performance is poor. The influence of VMI with consignment on the performance of the supply chain member is distinct depending on the individual member and time. The consignment may not be helpful to increase the system profit, but it reduces the manufacturer's burden of costs. Conclusions: VMI with consignment improves the supply chain performance after all, and it still takes times until its benefit becomes fully realized. To be a successful collaboration program, VMI with consignment requires a carefully designed incentive scheme that provides the timely compensation to the individual supply chain members. This study also finds out that the consignment contract of this collaboration program plays a role of financially supporting the manufacturer at the early stage of its implementation.

해쉬체인은 계산속도가 빠른 해쉬함수를 이용하여 체인을 구성하는 구조이다. 이 구조를 이용하여 화폐를 만들면 해쉬연산만으로 화폐의 유효성을 확인할 수 있어서 지금까지 주로 적은 금액이 빈번하게 교환되는 실명 거래 환경에서 응용되었다. 최근에 익명 거래가 가능한 범용화폐로 확장하려는 노력이 있었으나 추가 비용이 많이 들어 해쉬체인이 가지고 있는 본래의 장점이 퇴색하는 결과를 초래했다. 이 논문에서는 해쉬체인의 장점을 최대한 유지하면서 익명 거래와 분할이 가능한 오프라인 화폐를 제안한다. 이 화폐는 인출할 때 해쉬체인의 길이만큼 서명이 필요한 기존의 시스템과는 달리 한 번의 은닉서명만 수행하며, 다양한 금액을 추가비용 없이 지불할 수 있다. 새 시스템은 사용하고 남은 화폐에 대해서 환불이 가능하도록 하였으며, 환불티켓이라는 새로운 개념의 환불방식을 사용하여 지불과 환불을 연관시킬 수 없도록 하였다. 그밖에 지불액과 환불액 사이의 차액을 통해 관련 여부를 추측할 수 없도록 환불액을 축적하는 방식을 사용하고 있다.
