چکیده
We assume we have solved the problems (P) and (D), and that we have an optimal basis B ⊆ {1, 2, . . . , n}. Sensitivity analysis then refers to using to the basis B to solve a modified version (P’) and (D’) of the problems (P) and (D) from modified data A, b and c (whenever this information is useful). This is best done by example. Note that, if the optimal basic matrix AB remains unchanged, then B remains a valid basis for the problems (P’) and (D’). This is the main property that is used in sensitivity analysis.

Scheduling in a New Constraint Logic Programming Framework
Overview Constraint Logic Programming (CLP) has been an active eld of research during the past years and many programming languages have been proposed and some of them implemented to eeciently solve certain classes of problems. This project proposes a new framework for CLP, shows how the framework can be applied to a problem taken from Operations Research, and deenes a new language which implem...
متن کاملEmergency Response for Homeland Security: Lessons Learned and the Need for Analysis
Preface This report addresses response preparedness for large-scale emergency incidents, be they acts of terrorism, acts of Mother Nature (e.g., earthquakes, floods, tornadoes, hurricanes) or human-caused accidents. We call such events major emergencies, in which local first-responder resources are overwhelmed. There simply are not enough local resources to do the many jobs at hand. Response to...

Maximize ZD = b T y s.t. (D) A y + s = c, s ≥ 0n. where we have here chosen to add slack variables s ≥ 0n. The simplex method, as presented previously, works by starting with an initial basic feasible solution to (P) (which can be found via a phase 1 problem). However, what if a dual feasible basis is immediately available, whereas a basic feasible solution to (P) is harder to obtain? Can this ...
متن کاملChapter 4, Operations Research (or)
In the last chapter, we introduced the concept of a basis of a linear program (P) Minimize Z = c T x s.t. Recall that a basis of (P) is a subset B ⊆ {1, 2,. .. , n} of the variables. We also introduced the concepts of a basic solution x B of (P), and a dual basic solution y B associated with B and the dual (D) of (P). We finished by proving Lemma 1 Let B be an arbitrary basis for (P). If B is a...
