<dim:field mdschema="dc" element="description" qualifier="abstract" lang="en">Today's modern fishing industry creates a need to optimize production flow and product yield while reducing human labor. &#xd;
Valka, an Icelandic tech company, was in need of a new dynamic scale to offer more rapid weighing for sorting frozen fish pieces. The design proposed herein features a smaller weighing platform than previously employed, meant for sorting frozen fish pieces at a rate of 150 per minute with modular capabilities.&#xd;
	&#xd;
Axiomatic Design principles were applied in the development of the new design to systematically evaluate the design characteristic. All components were reviewed and the new design features smaller dimensions, a lower pitch conveyor belt and a different load cell with optimal capacity. Four configurations were tested; two spacing support piece materials and two types of load cell. Previous dynamic weighing products by Valka are capable of delivering a 95% confidence interval of +/-4g at a rate of 80 fresh fish pieces per minute. Therefore, the goal was to maintain this accuracy while measuring 150 frozen fish pieces per minute.&#xd;
	&#xd;
The results presented suggest that the optimal configuration is that with the Flintec PC6 load cell and a steel spacing support piece. The confidence interval of these measurements was found to be +/- 3,98 g, so the ideal was achieved.</dim:field>
<dim:field mdschema="dc" element="description" qualifier="abstract" lang="is">Valka býður upp á margar tæknilegar lausnir í fiskvinnslu hér á landi til að bæta flæði, nýtni og minnka nauðsynlegt vinnuafl. Þróun nýrrar útgáfu af dýnamiskri vog var nauðsynleg til að gera Völku kleift að flokka frosna bita hraðar en áður hefur verið boðið upp á. Hönnunin sem&#xd;
hér kemur fram kynnir nýjan, minni vogarpall en hefur áður verið nýttur. Þessi vogarpallur hreyfir bitana sjálfkrafa á færibandi og er ætlað að flokka frosinn fisk hraðar en áður með möguleika á fleiri, samsíða straumum.&#xd;
Forsemdur ítrunarhönnunar með frumforsemdum (e. Axiomatic Design) voru nýttar til að meta hönnunarkosti fyrri útgáfar og þróa hina nýju. Allir íhlutir voru sérstaklega skoðaðir með tilliti til nýrra krafna og nýja útgáfan er minni, stífari, hraðvirkari. Fjögur afbrigði voru sérstaklega prófuð; tvær undirstöðuplötur með mismunandi efni og tveir kraftnemar. Fyrri útgáfa vogarinnar hefur vigtað 80 ferska bita á mínútu með 95% vikmörk  4g. Markmiðið var að viðhalda sömu vikmörkum þegar 150 frosnir fiskbitar eru vigtaðir á hverri mínútu.&#xd;
Niðurstöðurnar sem hér eru kynntar benda á að besta afbrigðið sé notkun á Flintec PC6 kraftnema og stálplötu sem undirstöðu. Vikmörk voru staðfest sem  3; 98g, svo markmiðinu var náð. Lagðar eru fram tillögur að endurbótum sem eru líklegar til þess að auka nákvæmnina enn frekar.</dim:field>
