This third trial mutual relief maintenance model (MODEL H) is a more advanced one which has three modes of intervals Tp (port one) during home port, Tf (unrelieved one), Th (relieved one) within a propelling one Ts (=Tf+Th) and the corresponding three types of manpowers Mp (port relief one), Mf (inherent engines' one; =Ms), Mh (combined one) with a common complement Mc (Mh=Mf+Mc) between decks' and engines' department during Th than MODEL I (24 hours maintenance model) and MODEL II (8 hours one) of [1] ISSOA-'79 Tokyo and MODEL T (total one with home port relief) of [2] MESJ-'82. According to some results of GPSS digital simulation [3] with only two input data of occurring rate λ and man-hour per occurrence mh some useful trade-off relationships among many variables of total member MT (=Mp+Mf+Mc) and an equivalent complement ME (Tv⋅ME=Tp⋅Mp+Tf⋅Mf+Th⋅Mh) from due to a queuing length L and its rate l corresponding to some residual man-hour (ΔMH) are obtained by an important index of utilization η [4] which satisfies two necessary- and sufficientconditions with an allowable inventory Lc for MODEL H. Considering an overtime Ho the statistical results of simulation agree with the concept of theoretical queuing model for mutual system.
