Abstract
Regular and non-regular production can often be found in multipurpose batch plants, requiring two distinct operating strategies: campaign and short-term production. This paper describes a sequential approach for the simultaneous scheduling of campaign and short-term products in multipurpose batch plants. Campaign products follow a periodic scheduling and are constrained to a monthly demand and a safety stock level. Shortterm products have a non-periodic scheduling and must respect tight delivery time windows. Our integrated model is based on the Resource-Task Network (RTN) representation proposed by Pantelides (1994) and uses a discrete-time formulation.

Abstract
Virtual Enterprise is one form of collaborative networks that allows partners to exploit emerging business opportunities in a flexible way. Moreover, in the competitive landscape of the twenty-first century, the business model innovation has become increasingly a key element for companies' positioning in the market. Consequently, this paper aims at proposing a set of business model elements to be used by a virtual enterprise in order to explore a new business opportunity for its network. Literature review is used to identify the business model elements and evidence from a pilot case study confirms that these elements are considered in practice.

Abstract
The reality in today's business is to compete with dynamic and shorter market opportunities. In order to cope up with such environment, manufacturing firms, especially small and medium size enterprises (SMEs) are needed to collaborate with each other for mutual benefits. This collaboration offers process enhancement within the environment of virtual enterprise (VE) and contributes towards sharing costly resources and valuable knowledge among manufacturing companies. This research is basically focused on the process collaboration among companies that motivates them achieving identified business opportunities. A collaboration framework is proposed in this paper with respect to VE process mapping. Visualization of such processes is also highlighted though 'Dashboard' user interfaces in order to monitor and control a successful VE.

Abstract
Design and production of small series for specific customer target groups in collaborative networks can help companies to increase their competitiveness. This paper aims to describe a new framework of services for collaborative networking for on-demand productions. After describing the business processes that need to be supported by innovative tools for partner search and collaborative production planning, we describe the developed services and how they are integrated to ease the communication between different activities. © 2012 International Federation for Information Processing.

Abstract
In order to address the market trends especially footwear companies are now forced to address the market and especially the individual customer with increased attention concerning the fulfillment of specific requirements. In that context, consumer needs and expectations of specific target groups such as diabetic persons are posing challenging opportunities. Reality has shown that the production of shoes for patients with diabetic foot is quite different from traditional footwear production. This occurs because each shoe has to be fully adapted for each patient and in accordance with a set of requirements prescribed by the podiatrist. This reality raises several procedural and information related constraints in the way the orthopedic manufacturer has to deal with the customer demand. Framed in this goal, the present work specifically addresses the information infrastructure support required for the diabetic foot patient's prescription process by proposing an overall approach based on web-based tools and innovative integration of technological solutions.
