These components are puttogether in radio assembly. The electronic boards are obtained from a supplier who has a one$-$week delivery lead$-$time. The aluminum chassis is fabricated internally and the fabrication lead$-$time is one week. The lead$-$time for assembling the radio is also one week. Only one shipment ofcompleted radios is made in a week, at the beginning of the week.Radio $$ Assembly $$ Lead $$ Time: $1$ week $$ Electronic BoardsLead $$ Time: $1$ week $$ Used: $2$ per $$ radio $$ ChassisLead $$ Time: $1$ week $$ Used: $1$ per $$ radio $$

It is the beginning of week $1.$ NORAN is planning fabrication and purchasing based on themaster schedule shown below. $($The only relevant weeks are those numbered $4,5,6$ and $7.)$ Themaster schedule requires $50$ radios to be shipped at the beginning of week $4,$ another $50$ to beshipped at the beginning of week $5,$ and so forth. There are currently $10$ electronic boards, and nochassis units or assembled radios, in inventory.a$)$ Using MRP logic, determine the schedule of planned order releases for radio assembly,electronic board purchase, and chassis fabrication that is required to meet the radio shippingmaster schedule. $(20$ points$)$Radio Shipping Master ScheduleWeek $1234567$Radio Shipment $000505010080$Radio Assembly RequirementsWeek $1234567$RequirementsInitial InventoryScheduled ReceiptsPlanned Order ReleaseElectronic Board RequirementsWeek $1234567$RequirementsInitial InventoryScheduled ReceiptsPlanned Order Release
