The term supply chain modeling refers to different processes used over the years to define, determine and understand an organization's supply chain. It recognizes that there are many types of businesses, each of which has unique supply chain requirements.

The increased competition in the global market has obliged firms to maintain high customer service levels while at the same time, to reduce cost and maintain profit margins [ 1 ]. In this context, firms need to be able to produce and deliver a variety of customized products at low cost, high quality and short lead time [ 3 ], while possessing high reliability and flexibility to ever-changing requirements [ 4 ]. On the other hand, the competitiveness of a company is continuously tested and determined by its participation in networks of customers, distributors, partners and suppliers [ 5 ].

Operations Research Models for Supply Chain Management and Design

Abstract Supply chain management has been recently introduced to address the integration of organizational functions ranging from the ordering and receipt of raw materials throughout the manufacturing processes, to the distribution and delivery of products to the customer.

Its application demonstrates that this idea enables organizations to achieve higher quality products, better customer service, and lower inventory cost. In order to achieve high performance, supply chain functions must operate in an integrated and coordinated manner.

Several challenging problems associated with integrated supply chain design are: 1 how to model and coordinate the supply chain business processes, specifically in the area of supply chain workflows; 2 how to analyze the performance of an integrated supply chain network so that optimization techniques can be employed to improve customer service and reduce inventory cost; and 3 how to evaluate dynamic supply chain networks and obtain a comprehensive understanding of decision-making issues related to supply network configurations.

These problems are most representative in the supply chain theory's research and applications. There are three major objectives for this research. The first objective is to develop viable modeling methodologies and analyzing algorithms for supply chain business processes so that the logic properties of supply chain process models can be analyzed and verified.

This problem has not been studied in integrated supply chain literature to date. To facilitate the modeling and verification analysis of supply chain workflows, an object-oriented Petri nets based modular modeling and analyzing approach is presented.

The proposed, structured, process-modeling algorithm provides an effective way to design structured supply chain business processes. The second objective is to develop a network of inventory-queue models for the performance analysis and optimization of an integrated supply network with inventory control at all sites. An inventory-queue is a queueing model that incorporates an inventory replenishment policy for the output store. This dissertation extends the previous work done on the supply network model with base-stock control and service requirements.

Instead of one-for-one base stock policy, batch-ordering policy and lot-sizing problems are considered. To determine the replenishment lead times of items at the stores, a fixed-batch target-level production authorization mechanism is employed to explicitly obtain performance measures of the supply chain queueing model. The validity of the proposed model is illustrated by comparing the results from the analytical performance evaluation model and those obtained from the simulation study.

The third objective is to develop simulation models for understanding decision-making issues of the supply chain network configuration in an integrated environment. Simulation studies investigate multi-echelon distribution systems with installation stock reorder policy and echelon stock reorder policy.

The results show that, depending on the structure of multi-echelon distribution systems, either echelon stock or installation stock policy may be advantageous. This dissertation presents a new transshipment policy, called "alternate transshipment policy," to improve supply chain performance.

In an integrated supply chain network that considers both the distribution function and the manufacturing function, the impacts of component commonality on network performance are also evaluated.

The results of analysis-of-variance and Tukey's tests reveal that there is a significant difference in performance measures, such as delivery time and order fill rates, when comparing an integrated supply chain with higher component commonality to an integrated supply chain with lower component commonality. Several supply chain network examples are employed to substantiate the effectiveness of the proposed methodologies and algorithms.

Design of an Integrated Methodology for Analytical Design of Complex Supply Chains

Despite the increasing interest in supply chain management SCM by researchers and practitioners, there is still a lack of academic literature concerning topics such as methodologies to guide and support SCM evaluation. Most developed methodologies have been provided by consulting companies and are restricted in their publication and use. We analyze the applicability of the proposed model based on findings from interviews with experts - academics and practitioners - as well as from case studies of three focal firms and their supply chains. In general terms, the methodology can be considered a diagnostic instrument that allows companies to evaluate their maturity regarding SCM practices. From this diagnosis, firms can identify and implement activities to improve degree of adherence to the reference model and achieve SCM benefits.

A literature review and gap analysis indentifies key limitations of industry best practice when modelling of supply chains. To address these limitations the paper reports on the conception and development of an integrated modelling methodology designed to underpin the analytical design of complex supply chains. The methodology is based upon a systematic deployment of EM, CLD, and SM techniques; the integration of which is achieved via common modelling concepts and decomposition principles. Guidelines for the application of each step of the methodology are described. Also described are recommended data collection methods and expected modelling outcomes for each step. The paper reflects on preliminary benefits gained during industry based case study modelling and identifies areas of potential improvement.

Внутри не было никакого лирджета. Он несколько раз моргнул затуманенными глазами, надеясь, что это лишь галлюцинация. Увы, ангар был пуст. О Боже. Где же самолет.

 Данные? - спросил Бринкерхофф.  - Какие такие данные. Танкадо отдал кольцо.

 - Танкадо оставил нам только один выход-признать существование ТРАНСТЕКСТА. Такая возможность. Последний шанс. Но мы его упустили.

Воздух в помещении становился все прохладнее. Чем глубже под землю уходил коридор, тем уже он становился. Откуда-то сзади до них долетело эхо чьих-то громких, решительных шагов. Обернувшись, они увидели быстро приближавшуюся к ним громадную черную фигуру. Сьюзан никогда не видела этого человека раньше.

Беккер понял, что, если его преследователь находится внутри, он в западне. В Севильском соборе единственный вход одновременно является выходом. Такая архитектура стала популярной в те времена, когда церкви одновременно служили и крепостями, защищавшими от вторжения мавров, поскольку одну дверь легче забаррикадировать. Теперь у нее была другая функция: любой турист, входящий в собор, должен купить билет. Дверь высотой в шесть метров закрылась с гулким стуком, и Беккер оказался заперт в Божьем доме.

Оставался только один выход, одно решение. Он бросил взгляд на клавиатуру и начал печатать, даже не повернув к себе монитор. Его пальцы набирали слова медленно, но решительно.

Вопрос национальной безопасности. За дверью послышалось движение, раздались голоса. Он постучал. Послышался голос с сильным немецким акцентом: - Ja.

Сьюзан почувствовала, как напряглось все его тело. Они вступили в опасную зону: Хейл может быть где угодно. Вдали, за корпусом ТРАНСТЕКСТА, находилась их цель - Третий узел.

 - Он умер от разрыва сердца. Сегодня утром звонили из КОМИНТа. Их компьютер через Интерпол засек имя Танкадо в регистратуре полиции Севильи. - От разрыва сердца? - усомнилась Сьюзан.  - Ему ведь всего тридцать лет.

 Прошу меня извинить, - пробормотал Беккер, застегивая пряжку на ремне.

Я сам позвоню этому… - Не беспокойтесь, - прошептала Сьюзан.  - Танкадо мертв. Все замерли в изумлении. Возможные последствия полученного известия словно пулей пронзили Джаббу. Казалось, тучный шеф отдела обеспечения системной безопасности вот-вот рухнет на пол.

Где же самолет. Мотоцикл и такси с грохотом въехали в пустой ангар. Беккер лихорадочно осмотрел его в поисках укрытия, но задняя стена ангара, громадный щит из гофрированного металла, не имела ни дверей, ни окон.

 - Когда я все закончу, я сообщу тебе код вызова лифта. И тогда ты решишь, уходить тебе или. Повисла долгая тишина. Сьюзан словно во сне подошла и села с ним. - Сьюзан, - начал он, - я не был с тобой вполне откровенен.

Через несколько секунд двенадцатитонная стальная махина начала поворачиваться. Она попыталась собраться с мыслями, но они упрямо возвращали ее к. Дэвид Беккер.
