“…The build-to-order supply chain (BOSC) model, a key operation model for providing services/products, has received more attention in recent years, car manufacturers S including [3]. In the BOSC model, production activities are not executed until orders from customers have been received, which can effectively reduce the costs of demand prediction and inventory and credibly reflect market demands.…”

Abstract-This paper presents a hybrid programming framework for solving multi-objective optimization problems in supply chain. The proposed approach consists of the integration and hybridization of two modeling and solving environments, i.e., constraint logic programming and mathematical programming, to obtain a programming framework that offers significant advantages over the classical approach derived from operational research. The strongest points of both components are combined in the hybrid framework, which by introducing transformation allows a significant reduction in size of a problem and the optimal solution is found a lot faster. This is particularly important in the multi-objective optimization where problems have to be solved over and over again to find a set of Pareto-optimal solutions. An over two thousand-fold reduction in size was obtained for the illustrative examples together with a few hundred-fold reduction in the speed of finding the solution in relation to the mathematical programming method. In addition, the proposed framework allows the introduction of logical constraints that are difficult or impossible to model in operational research environments.

“…suppliers may ask for smooth delivery rates while logistics may ask for high fleet utilization. XTO is very important due to the increasing global competition since multinational companies are trying to secure market share and improved profits by utilizing global supply chains (Gunasekaran and Ngai, 2009). The X-to-order concept is based on the following strategy: a value chain that produces quality products or services which are based on the requirements of a customer or group of customers and are offered at competitive prices within a short period of time by leveraging core competencies of corporate allies or suppliers that will provide necessary parts and support services.…”

In a challenging market, companies' ability to act faster is considered a basic advantage. From a value chain aspect, when a company cannot change its internal production processes and the external supply streams according to the demand requirements, this may lead to sales reduction or stock left-overs. X-to-order concepts [where X=Α(ssemble), Μ(ake)/Β(uilt) and Ε(ngineer)], are key types of supply chain planning, where the production process starts after the orders are placed. Those methods have caught the attention of both researchers and businesses because of the advantages they offer in business procedures and the customization of consumers needs. The aim of this paper is to present the framework of supply chain management of the X-to-order concepts in comparison to the make-to-stock model and depict the main differences between these two approaches.

“…Thus, the quest for criteria such as: a better final price of the product, reduction in the levels of interruptions and inventory, quick distribution or better methods of payment is essential for the maintenance of the business. For this to happen, it is necessary for the chain to manage in the best way possible its resources, its logistics, its inventory and its information Ngai, 2009). …”

“…In this scenario, inventory management through the supply chain stands out, for it has been a determining factor for the success or failure of many organizations Ngai, 2009). With this increase in complexity of the markets, the traditional statistical demand forecasting models, based on time series, no longer met the needs imposed on them by the more competitive supply chains regarding their adequate levels of inventory and interruptions (Bayraktar et al, 2008).…”

Inventory management through the supply chains is a theme that has always enticed managers throughout the world. Due to the increase in market competitiveness and complexity, the traditional statistical models of forecasting demand, based on time series, no longer met the needs imposed on businesses to maintain adequate levels of their inventory and supply interruptions. With the intent to meet these market demands, ERP systems appeared in the 1990's. Nevertheless, even if allowing for a more adequate level of inventory and supply interruptions achieved mainly by the optimization of internal processes and the reduction in lead time, ERP systems did not contribute to reach the SCM's desired levels of inventory that were aimed at by the more competitive businesses. This is because ERP limits itself to an internal analysis of the business. By contrast, inventory management depends on the consumption information (which is external to the business). Aiming to improve even further the level of 368 Salgado Junior, A. P., Novi, J. C., Pacagnella Junior, A. C. Vol.8, No. 2, 2011, p. 367-388 services delivered to the end consumer, new solutions have been developed, among them the e-SCM, which, since it makes consumption information available in real time, ends up being more dynamic and efficient than the traditional demand forecasting models, Therefore, the present study aims to analyze how the e-SCM can collaborate in maintaining adequate levels of inventory and interruptions in the supply chains. The hypothesis made is that the traditional statistical forecasting models, based on time series and isolatedly, are no longer adequate to adjust the demand, as the tools based on these models do not update the demand in real time and this is fundamental in the current business dynamics. The research method used was the study of multiple cases in a segment of a chain involving a large retailer, its Distribution Center and a supplier of home appliances. For the analysis of the data, the content analysis technique was used. As main results, it was observed that, after the integration of the chain segment by the e-SCM, there was a reduction in the level of the inventory (36.8% in retail and 18% in the industry) and in inventory turnover (from 18.3 to 5.1 days in retail and from 19.6 to 3.2 days in the Distribution Center), aside from the variation in the interruption (from 17.3% to 2.6% in retail and from 3% to 0.1% in the case of the Distribution Center). Therefore, the study brings forth strong indication that the integration of the chain through the e-SCM, may contribute to the SCM's competitiveness.Keywords: e-SCM. Demand Forecast.
