Narrative:

Expected runway 25R given last minute assignment abeam civet for runway 24R. Attempted to program FMS while first officer went to raw data. Automation engaged. FMS route contained too many discontinuities. Autoflight began turn south of civet. First officer immediately turned back to reintercept but ATC queried us as we were trying to descend to make crossing restrictions and reassume the arrival. ATC ended up giving us vectors to intercept the runway 24R localizer with hard altitude assignments. Uneventful approach and landing. The circadian rhythm disruption from the previous day's early arrival to our east coast destination coupled with an extremely heavy workload on the lax arrival contributed to this event. We observed no traffic conflicts. Also; late runway changes into lax are becoming more frequent and present a dangerous scenario due to the extremely heavy workload while descending; slowing; and remaining dealing with last minute issues onboard the airplane.

Title: LATE RWY CHANGE ON CIVET ARR TO LAX.

Narrative: EXPECTED RWY 25R GIVEN LAST MINUTE ASSIGNMENT ABEAM CIVET FOR RWY 24R. ATTEMPTED TO PROGRAM FMS WHILE FO WENT TO RAW DATA. AUTOMATION ENGAGED. FMS ROUTE CONTAINED TOO MANY DISCONTINUITIES. AUTOFLIGHT BEGAN TURN SOUTH OF CIVET. FO IMMEDIATELY TURNED BACK TO REINTERCEPT BUT ATC QUERIED US AS WE WERE TRYING TO DESCEND TO MAKE CROSSING RESTRICTIONS AND REASSUME THE ARRIVAL. ATC ENDED UP GIVING US VECTORS TO INTERCEPT THE RWY 24R LOCALIZER WITH HARD ALTITUDE ASSIGNMENTS. UNEVENTFUL APPROACH AND LANDING. THE CIRCADIAN RHYTHM DISRUPTION FROM THE PREVIOUS DAY'S EARLY ARRIVAL TO OUR EAST COAST DESTINATION COUPLED WITH AN EXTREMELY HEAVY WORKLOAD ON THE LAX ARRIVAL CONTRIBUTED TO THIS EVENT. WE OBSERVED NO TRAFFIC CONFLICTS. ALSO; LATE RWY CHANGES INTO LAX ARE BECOMING MORE FREQUENT AND PRESENT A DANGEROUS SCENARIO DUE TO THE EXTREMELY HEAVY WORKLOAD WHILE DESCENDING; SLOWING; AND REMAINING DEALING WITH LAST MINUTE ISSUES ONBOARD THE AIRPLANE.
