Joji wrote: John, an unexpected emergency disrupting a smooth-running precision JIT/Toyota Production System is a well known defect of the Japanese system. When everything is moving on the precisely defined schedules, the Toyota Production System enables manufacturers to have profitable operations but unexpected emergencies disrupting the schedules cause devastating results. The recent Niigata Earthquake and resulting stoppage of water supply to the plant caused Riken's loss of production capacity resulting in the loss of 120,000 automobile production of all the car manufacturers. Speaking of unexpected results of the earthquake, an environment-conscious Italian succor [sic-Joji really means "soccer"] team canceled their trip to Japan on the ground that the Kashiwazaki Nuclear Power Station leaked waste materials into Japan Sea forcing sponsors of the events to refund all the ticket holders.

The shutdown will force TEPCO to generate more power using fuel oil and coal, which at current world prices will cost them an extra several billion dollars. If the entire 8,200 megawatts is replaced with coal for a year, that will increase Japan's CO2 output by about 40 million tons (the article doesn't say whether that's tons of carbon or of CO2). In Japan, 31% of electricity is nuclear-generated, up from 6.5% thirty years ago. But only 35 of the country's 55 plants are currently running; the rest are down for various reasons. (I'm not sure what percentage of the plants have to be running in order to reach that 31% figure.) Some more detail on the piston rings: Toyota says group production losses will total 55,000 vehicles, about 0.6% of their global total goal of 9.34 million for the year. They claim they will make up the shortfall by the end of the year. About 60% of the vehicles Toyota produces here are exported. Among all twelve major automakers, output losses are expected to exceed 110,000 vehicles, nearly three times next-biggest recent disaster, the Great Hanshin (Kobe) Earthquake in 1995. The Hanshin quake was a much bigger humanitarian disaster in a nominally more important industrial and shipping region, but only caused auto production losses of about 40,000 vehicles. Riken is partially back in operation. Most or all of the auto plants are resuming production today or tomorrow, but probably not at full capacity for a while yet, so losses are likely to grow somewhat. --Rod ------------------------------------------- Archives: http://v2.listbox.com/member/archive/247/=now RSS Feed: http://v2.listbox.com/member/archive/rss/247/ Powered by Listbox: http://www.listbox.com
