Approximate algorithm of semi online scheduling on two uniform machines with a rejecting buffer(拒绝可缓冲的2台同类机半在线排序问题的近似算法)
研究了 2个拒绝可缓冲的同类机半在线排序问题.设有2台同类机M1,M2,速度分别为1和s∈[1,+ ∞),加工不允许中断,工件Jj按照列表在线到达,每个工件带有2个参数:加工长度tj、拒绝罚值pj(模型1中)或拒绝获益pj(模型2中),当工件到达时,可以被接受并分给某台机器加工,也可以被拒绝,需付出一定的罚值(模型1)或取得一定的收益(模型2),目标是在第1个模型中要求极小化机器最大负荷和拒绝工件的总罚值之和;第2个模型中要求极大化机器最小负荷和总收益之和.此外,在接受或拒绝的决策环节上提供一个缓冲区B,其容量为k≥1,任一时刻至多可以存放k个工件,当工件到达时,若缓冲区未饱和,则可暂时存入B...
