However, as supply chains are complex and interconnected, if a bottleneck occurs in any one part of the chain, accurately gauging its impact and addressing the problem present various difficulties. Therefore, a considerable amount of time is considered necessary to reconstruct supply chains. The third problem is uncertainty as to when constraints on electric power supply will be removed.
Electric power companies and other related parties are doing all that they can to, for example, resume operations of facilities to restore supply capacity. Firms are also taking various measures to address the situation. One such measure is changing working hours. For example, one firm in Kanagawa Prefecture has changed the working hours of some divisions.
