Abstract
Today, organisations suffer a tremendous pressure to become more agile, efficient, profitable and dynamic. The market presents itself as an area of severe competition, where the margin between success and failure is becoming tenuous. Some authors have noticed the importance of meaningful and reliable information as a prerequisite of successful management and high-quality decision-making. Multiple factors, in the business environment were shown to cause impact in the organisational performance, such as the market attractiveness, the resources availability, clockspeed-industry, the environmental predictability, decision velocity and market opportunity discovery. The purpose of developing this research work was essentially to respond the following questions: Can the organisation improve performance by monitoring the market dynamics, by compiling information for the strategic positioning identification and market opportunities discovery? Can the information gathered agile the decision-making and the strategic alignment with the market? The market attractiveness index calculation phase intends to quantify the data collected from the multiple indicators, and then determine an index, for each market in the evaluation process. This technique is divided in three main steps, which consist of: (1) Calculating the mass density by category (Macro-Environment, Micro-Environment and Organisation), followed by (2) the product calculation of each category by the main market and, finally, (3) the prioritization of the different markets in study. The development of a methodology for assessing the market attractiveness is considered to be very relevant in the global market scenario. It can help organisations to gain a greater awareness of market dynamics, speed up the decision process and increase its consistency, thus enabling the strategic alignment and the improvement of the organisational performance.

Abstract
Cutting and packing problems have been a core area of research for many decades. Irregular shape packing is one of the most recent variants to be widely researched and its history extends over 40 years. The evolution of solution approaches to this problem can be attributed to increased computer power and advances in geometric techniques as well as more sophisticated and insightful algorithm design. In this paper we will focus on the latter. Our aim is not to give a chronological account or an exhaustive review, but to draw on the literature to describe and evaluate the core approaches. Irregular packing is combinatorial and as a result solution methods are heuristic, save a few notable exceptions. We will explore different ways of representing the problem and mechanisms for moving between solutions. We will also propose where we see the future challenges for researchers in this area.

Abstract
The nesting problem is a two-dimensional cutting and packing problem where the small pieces to cut have irregular shapes. A particular case of the nesting problem occurs when congruent copies of one single shape have to fill, as much as possible, a limited sheet. Traditional approaches to the nesting problem have difficulty to tackle with high number of pieces to place. Additionally, if the orientation of the given shape is not a constraint, the general nesting approaches are not particularly successful. This problem arises in practice in several industrial contexts such as footwear, metalware and furniture. A possible approach is the periodic placement of the shapes, in a lattice way. In this paper, we propose three heuristic approaches to solve this particular case of nesting problems. Experimental results are-compared with published results in literature and additional results obtained from new instances are also provided.

Abstract
Real-world distribution problems raise some practical considerations that usually are not considered in a realistic way in more theoretical studies. One of these considerations is related to the vehicle capacity, not only in terms of cubic meters or weight capacity but also in terms of the cargo physical arrangements. In a distribution scene, two combinatorial optimization problems, the vehicle routing problem with time windows and the container loading problem, are inherently related to each other. This work presents a framework to integrate these two problems using two different resolution methods. The first one treats the problem in a sequential approach, while the second uses a hierarchical approach. To test the quality and efficiency of the proposed approaches, some test problems were created based on the well-known Solomon, Bischoff and Ratcliff test problems. The results of the integrated approaches are presented and compared with results of the vehicle routing problem with time windows and the container loading problem applied separately.

Abstract
Several e-business frameworks are currently available, which are aimed at modelling e-business. The aim of this article is to analyse and compare relevant industry-neutral and industry-specific e-business frameworks currently in use, emphasising their strengths and weaknesses towards seamless interoperability in a collaborative networked environment. Their main differences and similarities are underlined based on an analytical model for e-business frameworks comparison. The applicability of the Analytic Hierarchy Process multi-criteria method in e-business frameworks selection is discussed. These analytical approaches are then illustrated with two real cases from industry.

Abstract
The advances in information and communication technologies and economic factors impelled organizations to engage in new forms of collaboration, such as collaborative networks. They require adequate frameworks, architectures, tools and platforms to support interoperability among heterogeneous and geographically distributed organizations. Despite the high number of research projects in this area, existing tools and infrastructures, this objective has not been totally achieved. The aim of this research work is to advance the research in the area of interoperability in collaborative networks. A conceptual framework towards seamless interoperability in a collaborative-competitive economic networked environment is described, which comprises six elements: (1) a messaging service: (2) a collaboration profile/agreement definition and management service; (3) five clusters of collaborative activities: (4) a centralized repository; (5) a set of business documents and a set of contracting documents; (6) a performance assessment service. The functionality of the conceptual framework proposed is illustrated with a real implementation case targeting the footwear industry. The proposed conceptual framework is then compared with relevant e-business frameworks.
