Sometimes beginning the discussion about an anticipated project is difficult. Perhaps each team member has a different idea of how to proceed; perhaps no one has an idea how to proceed. The assistance and guidance of a neutral third party with expertise can often help to start the ball rolling in the correct direction. And, keep it going in the right direction over time should that be needed. Donna Cohen is gifted at facilitating discussions among key players. She elicits staff concerns, ideas and priorities in a comfortable setting. You may choose to
have an individual discussion or brainstorming session and receive a brief summary report. Or, you may decide continued facilitated meetings would be useful. In either event, D. L. Cohen Information Services will help get your information project off to a solid start. Settings where this service may be of use: You need assistance to establish your initial information goals and strategies. You would like to develop or remodel a public website or intranet. You would like to develop or enhance a virtual and/or physical library or information center. Various methods for choosing among alternatives The various methods for choosing among alternatives are as follows: 1. Visual Interactive Goal Programming, 2. Supplier Selection I. Visual Interactive Goal Programming Visual Interactive Goal Programming (VIG) is a decision support system (Korhonen, 2007) based on a multi-criteria technique known as Pareto Race (Korhonen & Wallenius, 2006). This method treats constraints as a subset of purchasing teams' goals. Constraints of the problem define the feasible but not necessarily optimal solutions. Among these, there are some solutions such that no other feasible solution will yield an improvement in one goal (objective) without degrading the value of another goal (objective). These feasible solutions are referred to as "non-inferior", "efficient", "non-dominated", or "Pareto optimal" solutions. The method asks the decision-maker to give target values for each goal. It then finds the deviation of each goal from the target value, thereby defining a reference direction. Finally, it projects the reference direction on the set of non- dominated, efficient solutions. Therefore, in multiple criteria problems the notion of the optimal solution is replaced by the concept of the "best compromise solution".
Compromise solution is the efficient and non-dominated solution that is selected by decision-makers as their preferred solution among alternative courses of action provided by the technique. In VIG, while the goals of the decision-maker are termed flexible goals, constraints are called inflexible goals. This helps to formulate both goals and constraints similarly and to examine them simultaneously. The goal functions can be specified (i.e., minimize (</=) or maximize (>/=)). VIG starts by finding the best possible value for flexible goals. If some goals are defined as inflexible, VIG may not be able to find a feasible solution during the initial process. However, the method still
