Abstract: A self-tapping expansion bolt provided by the present invention contains a body, an expanded extension, and a nut. The body includes a drilling head and a grip. The drilling head has a cutter, at least one discharge trench, an expandable support portion, and outer threads. The expanded extension includes a first segment, a second segment, and multiple cutouts spirally surrounding from the first segment to the second segment. A spirally surrounding direction of the multiple cutouts is opposite to a rotating direction of the drilling head, and the expanded extension further includes multiple flexible sheets, a respective one sheet is defined between any two adjacent cutouts. A positioning manner is defined between the first segment and the expandable support portion, and the multiple cutouts are aligned and connected with the multiple discharge trenches of the drilling head. The nut is screwed with the outer threads of the body.

Abstract: Computer software for execution by a computer management system to supervise and detect a Boundary Conservation of Value and Quantity in at least one Supply Chain Unit Cell or Cell Group. A warning is output when there is an abnormality detected in the value or quantity in a supply chain unit cell or cell group, and corrective information is provided to the computer management system. A mathematical management logic model of supply Chain Boundary Conservation of Value and Quantity is utilized to perform the management of Supply Chain Boundary Change of Quantity or Value to supervise and detect a quantity or value of raw material, semi-products, as well as finished goods.

Abstract: The invention is a computer management system in application of Supply Chain Unit Cell or Cell Group or Boundary Conservation of Value and Quantity, which is a pioneer invention that has never been made known to the public up to this date. The following mathematical management logic model of supply Chain Boundary Conservation of Value and Quantity is utilized to perform the management of Supply Chain Boundary Change of Quantity or Value: ? i = 1 i = m ? ? ? INPUTi + ? i = 1 i = n ? ? ? UCi + ? i = 1 i = n ? ? ? ADJi ? ? . or ? . MCi = ? i = 1 i = p ? ? ? OUTPUTi + ? i = 1 i = n ? ? ? UCi ? The invention is specifically appropriate to apply to the supply chain management system concerning any change of quantity or value of raw material, semi-products as well as finished goods etc. It can also be used among the electronic business computer systems in various enterprises supply chain cell groups.
