Disclosed herein is an optimization method in a polymerization system in which heat is generated during the polymerization with an initiator. The optimization method includes the steps of measuring the heat generation amount based on the composition of the initiator in the polymerization system to previously set the relationship between the initiator composition and the heat generation amount, measuring the heat removal amount based on the temperature of a coolant in a cooling system of the polymerization system to previously set the relationship between the coolant temperature and the heat removal amount, calculating the initiator composition allowable at a predetermined coolant temperature to previously set the relationship between the coolant temperature and the initiator composition, and measuring the temperature of the coolant before and/or during the polymerization to adjust the composition of the initiator added at the measured temperature to the optimum condition, thereby decreasing the reaction time, and therefore, improving the productivity.

Method for optimization of process by adjustment of initiator in polymerization system

A vehicle dispatch system enables optimal dispatch of a plurality of vehicles with information of available vehicles from transportation company terminals and information of orders from client terminals under restrictive conditions such as vehicle sizes, minimum loading rates, and a maximum number of assignment locations, based on transportation regions preset in consideration of transportation times, past order quantities, and order congestion degrees, such that a relevant vehicle can perform delivery of freight within a predetermined transportation region to minimize a total transportation cost for each transportation region. The system minimizes a delivery distance of each vehicle, increases a loading volume of the vehicle to reduce an empty rate of vehicles, and minimizes the number of dispatched vehicles, thereby reducing the total transportation cost.
