    Chung and Wee [Chung, C.J., Wee, H.M., 2007. Optimizing the economic lot size of a three-stage supply chain with backordering derived without derivatives. European Journal of Operational Research 183, 933-943] investigate the economic lot size of a three-stage supply chain with backordering derived without derivatives. Their inventory model is correct and interesting. Basically, they adopt an algebraic approach by using the method of complete squares to locate the optimal solution of the integrated system's total cost TC(q,B,n,M) and ignore the role of the functional behavior of TC(q,B,n,M) in locating the optimal solution of it. However, as argued in this paper [Chung, C.J., Wee H.M., 2007. Optimizing the economic lot size of a three-stage supply chain with backordering derived without derivatives. European Journal of Operational Research 183, 933-943] need to explore the functional behavior of TC(q,B,n,M) to justify their solution. So, from the viewpoint of logic, the derivations about the optimal solution have some shortcomings such that the validity of the solution procedure in Chung and Wee [Chung, C.J., Wee H.M., 2007. Optimizing the economic lot size of a three-stage supply chain with backordering derived without derivatives. European Journal of Operational Research 183, 933-943] is questionable. The main purpose of this paper is to overcome those shortcomings and present complete proofs for Chung and Wee [Chung, C.J., Wee H.M., 2007. Optimizing the economic lot size of a three-stage supply chain with backordering derived without derivatives.

    Audio - Mr. Whiteley recounts the story of delivering the message of the flood of 1904. He took seventeen hours by horse to travel from Perryvale to Edmonton. Billy Loutit took the same message by foot arriving in Edmonton about the same time. Mr. Whiteley discusses early settlers, farming, homesteading and businesses. He has many anecdotes about life and people living in Athabasca at the start of the twentieth century. He freighted for ten years with the Hudson's Bay Company and also discusses early farming prices and technology extensivelyInformative Interview of Mr. C.J. Raymor Whitely In April 1961 on a Reel to Reel tape recorded onto cassette by R. Tanhas March 198
