    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">网络计划的工期优化可按下列<span style="color: black;">过程</span>进行：</span></span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">（1）</span><strong style="color: blue;"><span style="color: black;">确定</span></strong><span style="color: black;">初始网络计划的计算工期和</span><strong style="color: blue;"><span style="color: black;">关键线路</span></strong><span style="color: black;">。</span></span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">（2）按<span style="color: black;">需求</span>工期</span><strong style="color: blue;"><span style="color: black;">计算应缩短的时间ΔT</span></strong><span style="color: black;">：ΔT=Tc-Tr</span></span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">式中 Tc—网络计划的计算工期； Tr—<span style="color: black;">需求</span>工期。</span></span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">（3）<span style="color: black;">选取</span>应缩短<span style="color: black;">连续</span>时间的关键工作。</span><strong style="color: blue;"><span style="color: black;"><span style="color: black;">选取</span>压缩对象</span></strong><span style="color: black;">时宜在关键工作中<span style="color: black;">思虑</span>下列<span style="color: black;">原因</span>：</span></span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">1）</span><strong style="color: blue;"><span style="color: black;">缩短<span style="color: black;">连续</span>时间对质量和安全影响不大的工作</span></strong><span style="color: black;">；</span></span></p>

    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">3）</span><strong style="color: blue;"><span style="color: black;">缩短<span style="color: black;">连续</span>时间所需<span style="color: black;">增多</span>的<span style="color: black;">花费</span>最少的工作</span></strong><span style="color: black;">。</span></span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">（4）将所选定的关键工作的<span style="color: black;">连续</span>时间压缩至最短，并</span><strong style="color: blue;"><span style="color: black;">重新确定计算工期和关键线路</span></strong><span style="color: black;">。若被压缩的工作变成非关键工作，则应延长其<span style="color: black;">连续</span>时间，使之仍为关键工作。</span></span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">（5）当所<span style="color: black;">相关</span>键工作的<span style="color: black;">连续</span>时间都已达到其能</span><strong style="color: blue;"><span style="color: black;">缩短的极限而寻求不到继续缩短工期的<span style="color: black;">方法</span></span></strong><span style="color: black;">，但网络计划的计算工期仍<span style="color: black;">不可</span>满足<span style="color: black;">需求</span>工期时，应对网络计划的原技术<span style="color: black;">方法</span>、组织</span><strong style="color: blue;"><span style="color: black;"><span style="color: black;">方法</span>进行<span style="color: black;">调节</span></span></strong><span style="color: black;">，或对<span style="color: black;">需求</span></span><strong style="color: blue;"><span style="color: black;">工期重新审定</span></strong><span style="color: black;">。</span></span></p>
