Sellmore 問題之相關資料 試算表模式 指派問題之模式 已知一組需要執行的工作以及一組可以執行這些工作的人員,問題是決定哪位人員該指派哪項工作。 若是問題為指派模式,則必須滿足以下幾項假設: 被指派人數與工作數目要一樣多。 每位人員恰好被指派一項工作。 每項工作恰好被一位人員執行。 每組人員與工作的配對組合均涉及某一成本。 目標為決定應該如何來分派每位人員工作可使總成本為最低。 * * Table 3.1 Cost and exposure data for the Super Grain advertising-mix problem * * Table 3.2 Data for the TBA Airlines problem. * * Figure 3.2 A spreadsheet model for the TBA Airlines integer programming problem where the changing cells, Units Produced (C12:D12), show the optimal airplane purchases obtained by the Solver and the target cell, Total Profit (G12), gives the resulting total profit in millions of dollars. * * Table 3.3 Financial data for the projects being considered for partial investment by the Think-Big Development Co. * * Figure 3.3 The spreadsheet model for the Think-Big problem (Section 3.2), including the target cell Total NPV (H16), the changing cells Participation Share (C16:E16), and the optimal solution obtained by Solver. * * Figure 3.4 A template of a spreadsheet model for pure resource-allocation problems. * * Table 3.5 Data for the Union Airways personnel scheduling problem * * Figure 3.5 The spreadsheet model for the Union Airways problem, including the target cell Total Cost (J21), the changing cells Number Working (C21:G21), and the optimal solution as obtained by the Solver. * * Figure 3.6 A template of a spreadsheet model for pure cost-benefit-trade-off problems. * * Table 3.6 Types of Functional Constraint
