Chapter 2 Related work 2.1 Introduction: Multiple constraint satisfaction problems (MCSP) is a problem in which a set of values must meet a number of constraints. it has been widely used in AI to solve a wide range of problems. In this thesis we use MCSP to solve the load balancing proble. Therefore, we first review the different algorithms in MCSP and the Dynamic MCSP then we review the load balancing problem. 2.2 Constraint Satisfaction Problem: CSPs are mathematical problems which are defined as a set of values that must meet a number of constraints or state restrictions. The problem is to search for a set of values for the features (or variables) so that the values satisfy some conditions (or constraints). A CSPs consists of a set of variables; For each variable, a limited range of possible values (domain); and a set of constraints that restrict the values of variables that can be taken at one time. CSPs solution is to assign a value for each variable, in such way that all assignment satisfy all restrictions or constraints. Since the possible values of the variables are limited, thus this kind of problem is combinatorial in nature and NP-complete. Formally, A CSP is defined as a triplet (X , D, C) where …show more content…
there is no consistent partial solution. it revises the variables by using hill-climbing (Makoto and Katsutoshi, 1996) search untill it reaches the ideal solution. The min-conflicts heuristic (Minton, et al., 1992) is a local search for solving CSPs. This heuristic chooses randomly variable in the scope of the restriction violated, and assigns it to a value in its domain that reduces the number of restrictions violated. If there is more than one value, it randomly selects among them. but the main weak point of the min-conflicts heuristic is that the possibility of being caught in a local, non solution minimum, which leads to restart the algorithm from a new initial

Well-defined problems are those that have clear, defined goals and can be met in a formal and set number of steps. An example of a well-defined problem would be a math equation such as 2(x) + 4 = 10. In order to understand how to solve said problem first we ought to know the meaning of the mathematical symbols and numbers, and define the goal, which in this case is to figure out the value of “x”. We have to know that “( )”; aside from their typical use in writing, tell us to enclose and multiply whatever numbers or symbols are between them with the numbers or symbols outside of them; as well as recognize that “+” means addition or more. We must also infer that since the whole equation has to equal to 10 after being multiplied by...
How did Steve Heller define the problem describe in this case? How did Pam LaBlanc define the problem? How did the problem definition affect the way these two people initially solved the problem?
Problem solving is the process of following a series of steps to obtain the solution
Triple constraint refers to three important dimensions of a project that must be coordinated and balanced for successful completion of the project. The three constraints are interdependent because altering one constraints affects at least one other constraint. The triple constraint components include scope, time, and cost. The scope of a project refers to specific goals, deliverables, and tasks that must be accomplished for successful delivery of the end product. It must be defined and understood from the beginning of the project to allow effective allocation of resources. Basically, scope is a document that provides an understanding of what should be included and excluded from the project. Time or schedule is

The main problem is fundamentally related to supply chain problems, including duplication and inefficiency of sourcing, manufacturing and distribution. Therefore, task #1 is to optimize supply chain and squeeze costs.
Problem solving is defined as cognitive processing directed toward achieving a goal, including problem representation.
DSS is a system which aids management in some stages in the decision process in situation where some aspects of the process are not well structured or well defined. Decision support software can assists the decision maker in each of the steps in Figure 17-1. It can signal the need for a decision through an exception report. Software can be used to accumulate and organize the data so that managment can be better understand the nature of the problem. It can be used ...
The range of task environments that can be characterized by well - defined problems is vast. We can distinguish between so - called, toy problems, which are intended to illustrate or exercise various problem - solving methods, and so - called real - world problems, which tend to be more difficult and whose solutions people actually care about. In this section, we will give examples of both. By nature, toy problems can be given a concise, exact descri ption. This means that they can be easily used by different researchers to compare the performance of algorithms. Real - world problems, on the other hand, tend not to have a single agreed - upon description, but we will attempt to give the general flavor of t heir formulations.
The set-theoretic representation is one of the ways to represent a planning problem. Given a finite set $L$ of propositions, we can describe the environment as following:
CSR is a commonly used as an abbreviation for “Corporate Social Responsibility”. It is the corporate plan to assess and take liability for the organization’s effects on the environment and impact on social welfare. It’s basically a company's commitment to values that benefit society in addition to itself and its shareholders. It includes procedures that support community services, giving to charity, fair trade, environmental protection, as well as equitable business dealings with customers, employees and business partners.
