    Transportation Problem
    (2023-08) Rajiv Chooramun - OUM
    This resource introduces the Transportation Model in Operational Research, a type of Linear Programming Problem focused on minimizing transportation costs. It explains balanced and unbalanced problems, solution methods (North-West Corner, Least Cost, Vogel’s Approximation), and includes examples demonstrating both cost minimization and profit maximization in real-world logistics.

    Linear Programming Problem Simplex
    (2023-08) Rajiv Chooramun - OUM
    This resource introduces Linear Programming (LP), a mathematical technique for optimizing objective functions under given constraints. It covers LP formulation, feasible and optimal solutions, and real-world applications in Mauritius. Examples demonstrate both maximization and minimization problems, including resource allocation and cost reduction using the Simplex Method.

    Inventory Model
    (2023-08) Rajiv Chooramun - OUM
    This resource introduces inventory models in operational research, focusing on optimizing stock levels to balance ordering and carrying costs. It covers deterministic and probabilistic models, including EOQ, price-breaks, and manufacturing scenarios. The goal is to minimize total inventory cost while ensuring efficient production and distribution of goods.

    Critical Path Method and Project Evaluation Review Techniques
    (2023-08) Rajiv Chooramun - OUM
    This resource explores Network Analysis in project management, focusing on Critical Path Method (CPM) and Program Evaluation Review Technique (PERT). It covers activity scheduling, earliest start and latest finish times, float calculation, and critical paths. The techniques enhance planning efficiency, decision-making, and project control through systematic, graphical representations.

    UNIT II. DIFFERENTIATION: – Lesson № 4. The Differential Operators d(∙), D𝜉(∙) and the Principles of Differentiation
    (2024) UDM Lecturer Khodabocus M. I.
    Many important properties of a function of a variable are found with the aid of a related function called the derivative of the function with respect to the variable. Therefore, knowledge of the derivation of functions is clearly absolutely essential for further studies in so many engineering disciplines. Lesson № 4 introduces the definition and the basic properties of the differential operators d (⋅), Dξ (⋅). This is followed by a presentation of the principles of differentiation.
