Earlier CMP Trial and Robustness Controls

Historical development record. The controls on this page include earlier 100-draw settings and candidates that are not in the named SC14 release. They must not be used as the current CMP list. Use the SC14 CMP registry and release agreement report for the current eight-CMP set.

This page preserves the procedure settings recorded in the earlier tuns_ctrl.csv and robs_ctrl.csv files so that the development sequence can still be understood.

1 Tuning trials

These are procedure designs examined during earlier tuning. The table is not a current release control file.

Table 1: Settings for the 29 tuning trials. A dash means that the setting does not apply to that rule.

2 Robustness runs

The earlier robustness table applied MP29, MP32, MP43, and MP44 to nine alternative operating models. Each row below identifies one historical procedure–operating-model combination. The current 500-draw release instead contains all eight SC14 CMPs, listed in the release run index.

3 Reading the tables

  • Rule is the form of the harvest control rule.
  • Information source identifies the stock information supplied to the rule. all.idx means that all specified abundance indices are combined.
  • Limit is the indicator value at or below which the minimum catch applies.
  • Trigger is the indicator value at or above which the target catch applies.
  • Annual decrease and increase limits are multipliers on the previous year’s catch advice. For example, 0.85 and 1.20 limit a change to a 15% decrease or a 20% increase.
  • Operating model identifies the alternative description of stock dynamics used for robustness testing. See the MSE analysis for the assumptions that define each operating model.

The MP29 and MP32 pages document their current 500-draw sensitivity specifications. The registry and SC14 report record the complete eight-CMP refinement.
