Abstract: A road surface friction coefficient estimating device includes an electronic control unit. The electronic control unit is configured to: compute a system noise variance value as an index indicating a degree of variation in a road surface friction coefficient estimation value; compute an observation noise variance value as an index indicating a degree of variation in observation noise; compute, with regard to an observation deviation, an index indicating a degree of shift of the observation deviation that is newly obtained as to an index indicating a degree of past variation in the observation deviation; compute the index as a friction coefficient change amount; compute a Kalman gain; and add in the friction coefficient change amount when computing the system noise variance value.

Abstract: For enabling a execute of work start scheduling based on individual lot attributes, a production controller controls includes a lot schedule managing section for managing a first work estimate schedule for each of lots existing in finite buffer facility groups continuous in a working procedure, a facility schedule managing section for managing an operation stopping estimate schedule and a second work estimate schedule for each of facilities of the continuous finite buffer facility groups, and a buffer schedule managing section for managing a utilization estimate schedule for each of the finite buffer facility groups. With reference to the first work estimate schedule, the operation stopping estimate schedule, the second work estimate schedule, and the utilization estimate schedule, a continuous process scheduling section carries out scheduling of the lots put in a continuous zone of the continuous finite buffer facility groups.
