one-hour value [铁路] 小时值
Therefore, a relaxation of one unit in that constraint (an increment of one hour) would make the objective function's optimal value become better by the marginal value 1 and become 181.
因此，这个约束中放松一个单位（增加一个小时）可以使目标函数的优化值增加边界值 1，成为 181。
To realize the value of one hour
要想知道一小时的价值
A good production value is 3600 seconds (or one hour).
比较好的设置值为3600秒(或1个小时)。
