Watchdog system (Tanaka)
Past week report
I held a meeting to make estimates with several vendors.-->Price negotiation failed.Because the assumed price is too low(The estimate of the manufacturing cost of the chassis was higher than expected).
(Current assumed price about 900,000 yen -->Vendor's quotation price about 2,000,000 yen)
-->A different vendor submitted a quotation(It fits in the planned price). -->I also requested a new vendor to make a quote.
Waiting for concrete information on installation location.The type(High power,Low power)and number actually needed,and the peripheral equipment accompanying it.-->Placement plan for installing WDS in KAGRAJGW-E1707265(PDF).
