  7. 5. Multiobjective budgetary planning : models for interactive planning in decentralized organizations

    Författare :Nils-Göran Olve; Handelshögskolan i Stockholm; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Budgetary planning is typically concerned with identifying the best set of plans for the units of an organization. To achieve this, knowledge of possibilities and preferences is combined in a dialogue between the units and the central management. Often a single objective such as profit maximization or cost minimization is used. LÄS MER
