The formula is under 2 , over 1. Let me know if you think making a hammock, net or bag out of them would be an interesting Instructable :). Each section is 3 1/2" with an overall length of approximately 56". Previous control-theoretic models have identified as causes the tradeoff between stationary and dynamic performance[4] as well as the use of independent controllers. The system, nevertheless, is considerably sensitive to that behaviour; extreme over-reaction significantly reduces performance. The bullwhip effect was named by analogy with the way in which the amplitude of a whip increases down its length;[3] the further from the originating signal, the greater the distortion of the wave pattern. Overall length: 51? Don't forget to melt the ends before going on. Drop to a 6 plait ( under 2 over 1 ) as you progress.

You are now ready to begin plaiting the first layer. Regarded by some as one of the primary weapons of China, small enough to easily conceal but deadly when unleashed.

The handle is cloth wrapped to help prevent slipping. When making the round turns, let the inner loop be out for a few turns every now and then. Double the measurements. Take some time time to make this really tight. Omega, the International Journal of Management Science, 31 (3), 157–167.

Great design, excellent and clear instructable. See the last picture to see what goes where. You will then have to put the corresponding lengths of chain into the corresponding strands and this can be a real pain without the proper technique. Because customer demand is rarely perfectly stable, businesses must forecast demand to properly position inventory and other resources.

In such situations, it has been found that biased policies (both under-estimating and over-estimating the pipeline) perform just as well as unbiased policies.

The theory behind it is quite simple: you will use each of the 5 strands in turn to make a half hitch around ALL the other strands. On the bullwhip and inventory variance produced by an ordering policy. 7–7. The effect is that variations are amplified as one moves upstream in the supply chain (further from the customer). Quantitative Models for. You might want also want to mark the spots where the whips goes thinner, it will make it easier to know when to drop strands on the next layer. Text, image, video. You can run it once or twice around a soft round spot to make it even if you want. Have fun and play safe! However, studies suggest that people with increased need for safety and security seem to perform worse than risk-takers in a simulated supply chain environment. The technique remains the same. It is always possible to find a biased policy that outperforms an unbiased policy for any one performance metric. Trim the cords close to the whippings ( not to close so as not to let them spill open ). You will need: For the guts : -    x1    2m strand  ( 6.5ft ) -    x1    1m strand   (3.30 ft ) -    x1    80cm strand   ( 2.6ft ) -    x1    50 cm strand (1.6 ft) along with the corresponding 3 lengths of  lamp chain for the shorter ones : -    90cm   (2.95ft ) -    60 cm   (1.95ft ) -    30 cm   (1ft ) The first layer wil be a 8 strand round plait ( 4 strands folded in half will make it neater ) -     2x 5m       -> 4x 2,5       (16.4ft ) -     1X 3m      ->  2x 1,5      (9.90 ft) -     1x 4,30m -> 2x 2,15     (14.10 ft ) The outer layer will be a 12 strand plait ( again, 6 strands folded in half ) -    2x 7,30m   (24 ft)     -    1x 5,50m   (18 ft )  -    1x 5m         (16.4ft) -    1x 4,30m   (14.10ft ) -    1x 3m         (9.90 ft ) Please note that this is not an exact science.
