A work machine management apparatus includes: a switchback point setting unit configured to set a plurality of switchback points of a work machine in a work place of a mine; a work point setting unit configured to set at least one work point of the work machine in the work place; a travel track generating unit configured to generate a plurality of target travel tracks along which the work machine travels in the work place based on a position of the at least one work point and a position of each of the plurality of switchback points; and a travel track selecting unit configured to select, among the plurality of target travel tracks, a target travel track along which the work machine travels in the work place.

Work machine management apparatus

The present invention relates to a polyamide resin composition comprising polyamide (X) comprising a diamine unit containing 70 mol % or more of a metaxylylenediamine unit and a dicarboxylic acid unit and an alkali compound (A), wherein the following equations (1) to (3) are satisfied:0.03&#x2266;&#x3c;0.32&#x2003;&#x2003;(1)2.2&#x2266;&#x2266;26.1&#x2003;&#x2003;(2)5&#x3c;&#x2266;200&#x2003;&#x2003;(3)wherein P represents a mole concentration (&#x3bc;mol/g) of a phosphorus atom contained per g of the polyamide resin composition; and M represents a sum (&#x3bc;mol/g) of values obtained by multiplying a mole concentration of an alkali metal atom and a mole concentration of an alkaline earth metal atom each contained per g of the polyamide resin composition by valencies thereof respectively.
