Question 3

Problem 75-3 A contractor intends to bid on a job installing 30 airport security systems. Because this will be a new line of work for the contractor, he believes there will be a learning effect for the job. After reviewing time records from a similar type of activity, the contractor is convinced that an 85 percent curve is appropriate. He estimates that the first job will take his crew eight days to install. Use the following table for calculation. Learning curve coefficients 708 75% 80$ 85 % 908 Unit Unit Total Unit Total Unit Total Unit Total Unit Total Number Time Time Time Time Time Time Time Time Time Time 1 . 000 1 . 000 1 . 000 1. 000 1 . 000 1 . 000 1 . 000 1. 000 1 . 000 1 . 000 . 700 1. 700 . 750 1 . 750 . 800 1. 800 . 850 1 . 850 . 900 1. 900 568 2 . 268 . 634 2. 384 . 702 2.502 . 773 2. 623 846 2. 746 490 2 . 758 562 2 . 946 . 640 3. 142 . 723 3.345 810 3.556 JOUOWN 437 3. 195 513 3. 459 . 596 3. 738 686 4. 031 . 783 4.339 . 398 3.593 475 3.934 .562 4. 299 . 657 4. 688 . 762 5. 101 367 3. 960 .446 4. 380 . 534 4. 834 . 634 5. 322 . 744 5. 845 10 00 - . 343 4.303 422 4. 802 512 5. 346 . 614 5.936 . 729 6.574 323 4. 626 402 5. 204 493 5. 839 .597 6.533 . 716 7. 290 10 . 306 4.932 . 385 5.589 477 6.315 . 583 7. 116 . 705 7. 994 11 .291 5. 223 370 5. 958 . 462 6. 777 570 7 . 686 . 695 8. 689 12 . 278 5. 501 357 6.315 . 449 7.227 . 558 8 . 244 . 685 9. 374 13 267 5 . 769 345 6 . 660 .438 7 . 665 . 548 8 . 792 677 10 . 052 14 . 257 6. 026 334 6.994 . 428 8 . 092 . 539 9.331 670 10.721 15 248 6.274 325 7.319 418 8. 51 1 . 530 9 . 861 .663 11 . 384 16 . 240 6.514 . 316 7. 635 . 410 8 . 920 . 522 10.383 . 656 12 . 040 17 233 6. 747 . 309 7. 94 . 402 9. 322 . 515 10 . 898 650 12. 690 18 . 226 6.973 301 8 . 245 . 394 9 . 716 . 508 11. 405 . 644 13.334 19 220 7. 192 295 8. 540 . 388 10 . 104 . 501 11.907 . 639 13.974 20 214 7. 407 . 288 8 . 828 381 10 .485 495 12 . 402 . 634 14. 608 21 209 7. 615 . 283 9. 111 .375 10 . 860 . 490 12 . 892 630 15.237 22 204 7. 819 . 277 9 .388 .370 11. 230 . 484 13.376 . 625 15 . 862 23 199 8. 018 . 272 9 . 660 . 364 11. 594 . 479 13 . 856 . 621 16.483 24 195 8. 213 . 267 9 . 928 . 359 11. 954 . 475 14.331 617 17. 100 25 . 191 8. 404 . 263 10 . 191 . 355 12. 309 . 470 14. 801 613 17. 713 26 . 187 8 . 591 . 259 10. 449 . 350 12 . 659 . 466 15.267 . 609 18.323 27 183 8. 774 . 255 10 . 704 . 346 13.005 . 462 15 . 728 . 606 18.929 28 . 180 8.954 251 10 .955 . 342 13 . 347 . 458 16. 186 . 603 19.531 29 . 177 9. 131 . 247 11. 202 . 338 13.685 . 454 16 .640 . 599 20 . 131 30 174 9.305 . 244 11. 446 . 335 14.020 . 450 17. 091 . 596 20.727 How many days should the contractor budget for a.
