Problem 18-13 (Algo) Trucks arrive at the loading dock of a wholesale grocer at the rate of 12 per hour. A single crew consisting of two workers can load a truck in about 30 minutes. Crew members receive $10 per hour in wages and fringe benefits, and trucks and drivers reflect an hourly cost of $67. The manager is thinking of adding another member to the crew. The service rate would then be 2.4 trucks per hour. Assume rates are Poisson. Use Table 1 and Table2 10 a. Would the third crew member be economical? (Round your intermediate and final answer to 2 decimal places.) Answer is complete and correct. Yes became the total cost $ 97.00 b. Would a fourth member be justifiable of the resulting service capacity were 3 trucks per hour? (Round your intermediate and final answer to 2 decimal places.) Answer is complete but not entirely correct. 36.223 Yes v X MDF X M D F X M D F X MDF TABLE 18.7 Finito queuing tables 715 c 280 005 686 Population 125 2 082994 2803 0121 060999 1 575 520 2 019 1 095998 1302 nes 933 1 025 1 125 997 1 594914 2703 030 1 149 998 135 2 095933 2 034 1 168995 1 512 907 1 036 1 179 994 .140 2. 102 992 3 040 1 199 993 1 630 2 042 1 208952 3 011 1 044 1 218 991 2 10991 2804 046 1 228 990 1 647 892 3 050 1 247389 150 3 012999 2 052 1 2570 2 115 990 1 054 1 266 367 1 564 385 300 4 056 2 018389 155 3 013 999 3 1 276 SES 2 123 900 2 058 2 019 999 1 180 877 1 1 285384 180 2 015999 310 4 060 2 020 990 2 130990 3 1 295989 1 895 169 2 062 2 022999.186 3 016990 1 1 304 302 2 1379 320 4 054 2 023990 1 710161 3 314 581.170 3 017398 2 2 024 999 2 145985 1 1 333 979 1 725 853 330 4 068 2 326 999.180 3 0219 3 1 353 976 2 161 933 070 2 017 1 752 3336 1 1 34297 190 2 004 9983404 2 0019 2 .117 3 1 25 ST 1 718 819 2 080 2 05908 200 3 028 900 1 1 SES 2 19697830 4 OS 2 040992 1 301 301 3 1 410 210 3 332990 2 2 044998 2 21173 1 1 422 30 1 R2780380 4 016 1 099 220 2 991 1 5454 955 2 229 2 100 2 054 297 1 542 705 1 1 475230 2 041 997 4 105 7 2 147 25 3 1 345 1 247 110 2 1 0 046 926 1 1 516 300 2 265 .360 470 4 115 2 017 1 730 3 1 3250 a 12 052 1 2 010 2015 1 1 712 4 0589944403 238 560 303 $50 2 552 807 Soc95 1 992451 064 904 480 4 045905 323 266953 915677 2 .686787 071 993 1 994 432 342 938 480 4 053 994 925 651 3 296945 DOT 990 2 719 787 079992 1 996415 382932 500 4 063 992 934 614 3 327936 08999 2 .750 748 086990 1 997 399 382 928520 4 073901 942628 3 359 927 DO9 999 2 779728 091989 1 .998 384 402919 540 4 Das 999 950 613 3 392 917 01005 2 308 309 100 SSB 1 432 912 500 4 Se 597 3 A25 012999 2 31 889 11266 1 999 357 442 904 500 4 113954 962580 2 461 295 01329 2 854 70 121 905 1 999 345 1829 4 130 981 967569 3 4973 01790 2 141 581 1 501 380 4 375 542 3 5880 0219 2 sta 103 970 1 540 353.700 240 981515 3 578 015 52.97 2 550 560 1892 1 SN 15750 4 316 94 San 430 3 3 777 B01 97 2 972 RO 2:11 4 318 320 471 2 96700 906 OLE 856 906860 905 665 SLO 006 005 WSCH DE 66 LES OW 060 596 036 BOY WE OOR X MDF X M D F X MD FX MDF 166 7 066 7 C 999 596 c 850 4 522 900 054 1 3 .907 .702 066 2 2 995 470 1 900 4 556871 D68 3 3 957 566 2 2 988 444 1 .950 815 838 070 3 3 seg 631 2 Population 10 1 .016 1 144 997 075 3 019 1 .170 956 2 021 1 188 995 1 OZ3 1 206994080 3 025 1 224 933 2 028 1 232 992 1 028 1 250 991 0853 030 1 268 990 2 032 2 OGS 999 1 1 285 988 090 3 034 2 037 2 1 301 986 1 036 2. 041 095 3 1 2 038 2 1 1 337 962 100 3 2 050 999 2 1 354 980 1 042 2 055 999 105 3 1 371 978 2 0442 1 1 380 975 110 3 046 2 065998 2 1 404 973 1 048 2 071 998 115 3 1 421 970 2 .050 2 076 1 1 967 120 4 052 2 082 997 3 1 454 563 2 054 2 997 1 1 470 960 125 4 2 094 997 3 1 496 556 2 2 100 950 1 1 953130 4 060 2 106 996 3 1 517 546 2 062 2 113 998 1 1 945 135 00 2 2 565 795 OSE 665 10 547 940.1352 126 995 1 562 36.140 4 020 999 3 .133 .994 2 -577 931 1 022 999 145 4 .140 994 991 926 2 026 999 1 158 992.150 4 527 913 3 031 2 177 990 1 580 899.155 4 037 399 3 195 988 2 692 883 1 043 998 160 4 216 996 722 867 2 049 998 1 237 984 165 4 .750 650 056 998 2 258 981 1 776 832 170 4 064 957 3 279 978 2 814 1 0172 997 180 5 201 974 4 .795 3 081 998 2 324 971 1 303 776 190 5 016 999 4 995 3 346 367 2 756 1 019 999 200 5 .100 994 364 962 2 478 737 2 022 999 1 119 994 210 5 3912 958 4 198 718 025 999 z .121 993 1 415 952 220 5 030 998 907 699 4 .124 990 028 999 3 366 954 132 2 761 815 437 .947 1 993453 919 880230 5 037998 032 999 4 142 988 144 3 400 947 480 941 2 791 794 929662 1 996 434 038 990 240 5 014 987 156 989 162 986 483 935 434 S38 939 644 2 819 774 040 998 1 .996 416 169 987250 6 010999 505 928 5 052 997 947 -827 4 183 SS 044 998 3 469 929 .182 986 2 844 753 528 921 1 997 400 954 610260 6 013999 049997 5 .060996 .195984 4 205980 550 914 3 503 919 961 594 2 366 732 054 997 1 998386 209 982 270 6 015999 571 906 5 070995 566 579 4 228 978 013999 3 537 908 066 996 2 886712 238 378 1 999 370 514 890 280 018 999 975 890 5 081 994 015 999 4 252 972 078 995 3 571336 269 973 2 903 592 554 873 1 999 357 982 .522 290 5 022 020 999 osa 097 994 4 278 900 300 950 3 603284 892 854 918 672 97 497 1 -999345 025900 200 026 998 108 992 5 106 991 33961 4 300 83 728335 3 635 872 990 A74 010 065 800 9 050 990 TES
